A sharks life cycle is very interesting. We don’t really know that much about their life cycle because man has not been able to study many of the mating, birth, and lives of the over four hundred species of sharks that populate the world.

The few sharks that have survived in captivity and have been studied are where most of the “averages” that you read about come from. These are a fraction of the vast number of sharks that cannot be captured, held in captivity, or studied successfully in the wild.

The gestation period of a shark can last from 9 months to two years. The three methods for birth are the ovoparity in which eggs are laid in a crevice or crack in a protected area. The egg is a tough leather-like casing that is screwed into the crevice or crack so that it is hard for predators to retrieve.

Some sharks carry their eggs in the womb, called the ovoviparity method. When a pup hatches from the egg it feeds on the other eggs in the womb and the fluids, then is born fully developed and functioning. The viviparity method is the same as mammals. The pups are carried in a placenta, nurse and are weaned there and then are born and swim away from the mother.

A reason that there are over eight species of shark are threatened with extinction is because there is no regulations to protect them. Sharks are not like other fish that lay a lot of eggs and have several hundred babies every few months. Some sharks do not reach maturity until they are in their teens and have one or two pups every two years. With 30-100 million sharks being killed each year, there is not enough time for the shark population to recover.

On average, a shark lives up to twenty-five years. But, remember that there are no real statistics on sharks that we have not been able to study. No one knows for sure how long a Great White lives. A Great White that is being followed in the wild is currently 25 years old. There are Whale Sharks living that are thought to be at least 100 years old.

Studying sharks has always Seiji Tadashi’s passion for as long as he can remember and has always pondered about the sharks life cycle.

Searching for the best tankmates for South American Cichlids can be difficult at first. But it is not that hard if you make sure not to make any quick decisions when you are in your favorite pet store.

Considering how big your cichlids will be is the first thing that you should think about. Never pick tankmates for your cichlids that look like they are small enough to fit in your fishes mouth. Maybe that will not always work, but you get the idea.

Second, choosing tankmates that do not have the same temperament as each other. Juvenile Oscars and Angel Fish are a good example. These two species make great tankmates when they are little. But when those Oscars start to grow, the Angels will loose every battle very quickly.

Those are a few obvious points about choosing tankmates for your cichlids, but lets get to the issue of this article. So what are the best tankmates for cichlids. Catfish, that’s right, Catfish. But lets get a little bit more specific. What about Corydoras. These little guys are some of my favorite tropical fish, and they make great tankmates for all sorts of cichlids.

Again, you should definitely think about the size of the cichlids that you own. If you have Oscars, you should not choose the smaller kinds of corydoras. The Oscars will think that they are food and scarf them down like little candies. It is best to choose one of the larger varieties of corys like the bronze corydoras.

They will mature at about three inches long and make good tank mates for even the larger varieties of South American Cichlids, when the catfish are fully mature of course.

But consider this fact when choosing tankmates for cichlids, sometimes Oscars don’t play by the rules. It is best to raise Oscars with corys as tankmates so they get used to having them swim about the bottom of the tank. And make sure that you keep at least five or six corys at a time. They are much happier when they have a few buddies.

Most pet-lovers find breeding fish a relaxing hobby. Seeing the vivid yet relaxing colors of the fish refreshes stressed eyes and tired bodies. Because of this, betta fish breeding has been quickly gaining popularity among hobbyists and pet-lovers.

There is not much difficulty in taking care of betta fish because the only things you need are the male and female pair and of course, your ten-gallon aquarium. After this initial preparation comes conditioning-you need to feed your pair of bettas good food for two weeks straight before you can proceed with the breeding. As you condition your betta fish pair, you should prepare the breeding tank by cleaning it properly before actually starting the process.

Do not use soap in cleaning your tank, use searing water instead. Your aquarium should have at least six inches of water before you are able to add your sponge sifter and tank warmer. Read the necessary guidelines first about heating, aquarium bacteria starters, and water maintenance to ensure the best as you breed your betta fish.

You are now ready to put the fish into the tank so that he can already be adjusted to his new surroundings. It is necessary for the male betta fish to become familiar with his new habitat so you have to put him in the aquarium first and leave some time for him to know where he is. You may set up a divider before putting the female fish inside the tank because it is necessary to keep the fish pair separated for them to breed well.

You have to watch the actions of your betta fish pair before you remove the transparent dividers and let them interact with each other. To know that the male betta fish is ready for breeding, his fins should be flapping furiously around the female as he builds a bubble nest for the future eggs. On the other hand, the female is ready for breeding if you can see vertical bars on her body.

The vertical lines on the female betta fish’ body are quite hard to find if you’re breeding light-colored fish so you should observe your fish well before you make the next step. If you have confirmed that your female betta fish is ready for breeding, you should release her after a day or two after she first came into the tank. It is best to release the female at this period to ensure good interaction between her and the male fish.

Once the female and male betta fish are together, they will chase each other around the aquarium. The actions of the male betta fish such as running after the female’s fins will be quite rough but this is part of their “dance” with each other. If the female is finally ready to reproduce then she will be the one to approach the male fish which could happen in around two days.

Feeding is not important to the fish pair as they try to reproduce so even if you feed them, they wouldn’t notice this as they are focused on their breeding task. Normally, the fish pair will be tired and they will appear motionless which shouldn’t cause you to worry about them. In a while, the fish will begin moving normally, especially after the female betta fish releases all her eggs and the next step will be to leave the eggs with the male and separating the fish pair again.

You don’t always need to go scuba diving in order for you to appreciate marine life. You can set up your own marine fish tank or saltwater aquarium so you can enjoy the beauty of the sea. Marine fish tanks do not only satisfy marine life enthusiasts, but they can also add an interesting and beautiful attraction to any home or office. They actually make a good conversation piece.

Though you can easily purchase marine fish tanks and other equipment from various pet supplies stores, setting up your own saltwater fish aquarium is not that easy. You need more than just the equipment to get started. You also need a lot of information, patience, and commitment to maintain marine fish tanks.

Saltwater fishkeeping versus freshwater fishkeeping Salwater fishkeeping or marine fishkeeping is different from freshwater fishkeeping in that the requirements for marine fish tanks are more complex. Water parameters such as salinity, pH, specific gravity, temperature, and ammonia, among others, need close monitoring. Marine fish tanks have intricate filtration systems, including the need for protein skimmers that remove organic compounds before they degrade.

Aside from the equipment, you will also spend more on acquiring saltwater fish since they are usually more expensive than their freshwater counterparts. This is because they are usually more eye-catching and exotic. In addition, you will also have to invest in live rock. This can be the most expensive part of your initial setup for the aquarium as you may need to have the live rock cured. However, it is a worthy investment because it is considered as the best form of biological filtration, not to mention the beauty that it will add to your entire marine aquarium setup.

Getting ready for your marine aquarium setup

Setting up a marine fish tank entails a lot of effort, not to mention that it can also be costly. It need not to be too difficult though, especially if you are well informed about marine fishkeeping.

For setting up your marine ecosystem, you need an aquarium equipped with a filter, lighting device, and heater. These are very important since different marine creatures thrive in different temperatures. You should also take note that a marine fish tank requires more complex filtration systems. You will also need protein skimmers that remove organic compound prior to degradation.

When you purchase your aquarium, consider the types of fish that you plan to keep. Consider also the location where you will place the aquarium as it should be kept from external sources of light and heat. Pay extra attention to your live rock too. Live rock is composed of limestone and decomposing coral skeleton. These rocks need some curing and maintenance as well.

Once you’ve set up all the equipment, allow the tank to settle first before adding your fish. Of course, it does not end here. You need to perform regular aquarium maintenance such as cleaning and monitoring water salinity. Ideally, you should clean and change the water at least once a month.

A sharks senses have evolved with sharks to become an effective and efficient means of survival. It is interesting to note that because sharks have no other predator but man, they are not equipped with some of the defensive mechanisms of other sea creatures.

A sharks senses work in unison to make it an efficient predator that can sense injured animals and fish from several miles away. Experiments have been done on some shark’s to get an idea of how the senses of a shark work together with interesting results. When a shark’s nose is stopped up it has significant difficulty hunting, even though the sense of smell is not the primary sense. The entire body of a shark plays an important role in the effectiveness of the senses and it’s ability to hunt and survive.

Many sharks have light sensitivity that is ten times more sensitive than humans. They can see objects from 70-100 feet away. Depending on whether the shark is a bottom feeder or surface feeder, they may have extremely good eyesight or very poor eyesight. Researchers have found that Lemon sharks can detect colors and that they prefer bright shiny colors.

Two highly developed senses are hearing and smell. In tests on sharks in captivity, one drop of blood could be detected in 2,000 gallons of water. In the ocean sharks can smell blood from many miles. In addition, many sharks are attracted to the scent of chemicals in the gut and can be found at sewage outfalls. Another interesting feature of a sharks sense of smell is their ability to smell directionally. When a smell enters their nostrils, the scent enters the nostril first that is in the direction of the scent. Their hearing is received, unfiltered directly from the hole in their head to the inner ear. Sounds with a very low frequency are heard easily from as much a . 6 miles away.

Sharks have two senses that humans do not share. These senses give the shark an advantage as a predator and provide it with the ability to detect injured animals from a great distance. First, the head of the shark contains Ampullae of Lorenzine. These are small ampules that are electroreceptors. All animals, including humans emit an electromagnetic field. When injured, the electromagnetic field changes slightly. The receptors detect this change from several miles away and attracts the shark to the prey.

The Lateral Line is also unique to the shark. These tubes look a lot like an ear canal with tiny hairs along the length of each tube. They run along both sides of the shark and end in the brain. The Lateral Line is able to detect vibrations in the water from ten feet away and senses frequencies of 25-50Hz. If there is splashing or distress in the water, the shark can sense it with their Lateral Line.

When all of the sharks senses are combined they create a perfect method for a fish that spends most of its life hunting for prey that is hiding or moving in a vast ocean.

In her studies of sharks one aspect that has always fascinated Pam Golding is sharks senses.

Each component that makes up your aquarium environment plays a significant role in successful aquarium maintenance. However, before you go and buy fish tank materials, there are three key elements that you should look into if you want to achieve a beautiful aquarium. These include aquarium flooring, water, and plants.

Putting gravel or sand at the bottom of your tank is not always necessary, unless you are using rooted aquarium plants. If you find gravel more appealing than a sandy bottom, make sure to buy fish tank gravel that is the same size as-or slightly larger than-bird gravel to achieve the best results. Wash the gravel thoroughly before placing them inside your aquarium. Gravel works great with live plants, but if you prefer to use sand, choose a coarser variety. Fine sand is packed too tightly when wet, and this hinders the growth of underwater plants.

The most crucial aspect of aquarium care is the water, and unless it’s kept in top condition, your fish and plants will not thrive. The best water for fish keeping is conditioned water, or water in which the fish have lived. Oddly, the waste products produced by fish actually make the water more apt for fish to live in. Hence, you don’t need to remove all kinds of dirt. Only harmful substances, bodies of dead fish, and uneaten food should be removed. Thus, you may buy fish tank tools for getting rid of these.

If it’s your first time to set up an aquarium, be sure to let chlorine-treated tap water stand before exposing your fish to it. Chlorine is toxic to fish, and waiting for the water to be at room temperature gives you time to allow the chlorine to dissipate. Buy fish tank thermometers to keep an eye on water temperature, as this is critical in fishkeeping. Newly filled aquariums are normally murky. To provide clear water for your fish, give them a modest amount of food in the first two weeks.

Contrary to popular belief, fish don’t need live plants for oxygen supply and carbon dioxide release. This doesn’t make plants less important, though. If you wish for a more natural setting for your fish, a well-planted aquarium is a good playground for the fish. In terms of aesthetics, it doesn’t really matter much if you want to purchase plastic or live plants, rooted or not. However, live plants in good condition do keep the water from turning green.

Although plants are essential in an aquarium, it doesn’t mean that they are needed by the fish for breathing. Still, plants make a lovely backdrop and create an almost-natural environment for your fish. An aquarium with healthy, live plants is also less likely to have greenish water, which usually happens when there’s too much algae in your tank.

The amount of light your tank will need relies on your choice of plants to grow in your aquarium. Fanwort and water thyme require stronger light, while arrowhead, floating fern, and tape grass need less. They may be bought at stores selling aquarium supplies.

Setting up a beautiful and healthy aquarium is possible without having to spend so much money. If you look into the basics of fish keeping and ask yourself such questions, you’ll know which aquarium accessories you should prioritize.

When you are ready to go from being a tropical fish observer to a happy tropical fish owner, you’ve got some things to take care of. You need to make sure that this is something you are really ready to take on because while it’s quite wonderful to own tropical fish, it’s hard work, too. Have no fear; you will be greatly rewarded for your diligence. This tropical fish guide may make things a bit easier for you.

It is recommended that you purchase the tank and accessories prior to buying the fish. Your tropical fish will not be happy or healthy for long in a plastic bag. You need to establish a clean and safe environment for them ahead of time. Give them something magnificent to come home to. When buying your first tank, don’t think that bigger is better. Since you’re a newcomer to the world of tropical fish ownership, start small. Once you see that you are good at taking care of them, you can increase the tank size. Just don’t bite off more than you can chew out of the gate.

Many pet stores these days sell tank kits. They can be useful when you aren’t very familiar with what fish need to live and what they like. However, be careful that you don’t buy a kit that is cheaply made. It’s going to be a little bit expensive when you first start this venture. Don’t go the cheap route; you could end up putting your fish in jeopardy. Cheap parts can fall off and kill your pets.

You must purchase a strong and well built tank with a lid and a stand that will hold your fish tank. Also ensure that the tank does not have any cracks or obvious defects. You also will need to purchase a 5 watt light and a back filter with a hang for your fish tank to keep your new pets happy and healthy. Before you do anything, thoroughly wash your tank out with warm water when you get it home and make sure that the water is pure before you begin introducing fish into it. If you use any type of soap or detergent, it is important that you rinse your tank completely. You don’t want to poison your fish!

Buy colored gravel or pretty glass beads to line the base of your tank. The fish will enjoy this and it helps trap algae and other things that you may not want to see floating in your tank. You can buy all kinds of cool stuff to put in the bottom of the tank, make sure that if you buy any “hiding place” items for your fish, they’re big enough. The last thing you want is a fish injuring itself by trying to get into a space that’s too small for it.

Begin adding water and set your tank heater to approximately 80 degrees. This is the ideal temperature for most tropical fish. Be sure and check with the pet store before putting your fish in their new home.

Set up your light in the tank before adding your fish. Fish like light but having your tank directly in front of the window will cause algae to grow out of control and you’ll have a difficult time with regulating temperature. Once you’ve got the water added, gradually warm it and then get to the pet store! There are a lot of places you can buy tropical fish from. There are specialty shops that can order any kind of tropical fish for you if they don’t have them in stock. You can also buy tropical fish in most local pet shops.

Select breeds that are known to get along well together. Certain breeds are predatory and will eat each other. This is not what you want the children to witness. If the pet shop owner doesn’t know what kinds of fish get along the best, go do your own research before making your purchase or only buy one breed to start.

Take care when you go to feed your new pets. Tropical fish require a very specific diet and should be eating at the same time of day, every day. Never feed them too much and if you’re going away, have someone feed your fish. Take care of your tank and your fish should prosper. If you ever have problems, you can find the answers to your questions online. Good luck and enjoy your new tropical fish!

Fish are perfect for first pets. They are silent, contained, and not messy. They also allow children to learn responsibility over pets (in terms of aquarium maintenance) and can let them build up their skills toward tending to a more complex pet. You may have to start by cleaning the tank yourself and having your child help with small tasks before they can eventually fully take over.

Bigger aquariums tend to be much better than smaller. Though it is tempting to save money by buying the traditional bowl, the water will almost always be more easily contaminated. Bigger tanks can firstly support different filtration systems. Secondly, bigger tanks have more water, which means that if there is a slight impurity in the water, it will be less problem to the fish than being in a smaller bowl. More water means more dilution for imperfections.

You can also get more fish if you have a bigger tank. It is tempting to start out with one fish to see how your child fares, but the death of a single fish may be very upsetting to a child, while it may not be noticeable if there are many fish in the tank. It is also a better return for your money. Why buy all of the equipment for just a single fish?

Your goal is to keep the ecology in the tank as normal as possible. The fewer the fish, the less genetic diversity, and the more chance of an ecological disturbance if a fish is sick or dies. Think of how life really is in an live body or water.

The maintenance of a tank depends on what type of fish you have. If you have fresh water fish, you do not have to worry quite as much. If you have salt water fish, you need to measure the salt content of the water you put in. Salt may require specialized systems for briny species. It can be difficult to measure the levels.

The specific components of the system should be discussed with a professional at the pet store. They can help you fit the tank to your budget and your fish. There are a few things to do regardless of what type of system you have. Clean up any large messes, but most importantly you need to change out a third of the water and put in new about every two weeks. If you use EcoBio-Block products, you can reduce this part of your maintenance to once a month or less. EcoBio-Block contains beneficial bacteria that create a healthy environment for your fish. These bacteria which are found in nature, break down toxic organic waste into safer by-products, clarify your water and eliminate odors. All you have to do is put the block in the water and wait for the bacteria to build up in the tank. Just be sure to monitor your ammonia and nitrite levels on a regular basis.

The gravel at the bottom of the tank can be a pit for fish excrement and unnoticed food. It needs to be vacuumed occasionally. Check the filters every couple of weeks or so. You can also check the pH occasionally, but most fish can tolerate pretty wide extremes of pH levels as long as they are not suddenly changed.

Filter inserts should be automatically changed every month, even if you think they look fine. On a daily basis you should just watch life in the tank. Fish can bully or abuse others, or eat more than their share of food. You should count the fish to make sure one has not died and you may need to separate fish if there is an unhappy relationship.
