How straightforward is keeping a shark in a fish tank at home? Well, even though not all that difficult, you should know some tricks of the trade, like which variety should one go for and what size of the tank. Freshwater sharks are unique creatures, in that they often take a few weeks to get used to a new environment. As such the owner might not see their shark for quite some time in the beginning. After this, they will become territorial, and if they become stressed may even start fin nipping other fish. This is why it is advised, especially in smaller tanks of under 55 gallons, to include fast swimming and short finned neighbours. So a bigger tank is strongly advised, as this keeps all your fish happy and healthy. It is well-worth the extra money because sharks exhibit such interesting behaviour and are overall extraordinary as far as fish come. The Labeo sharks of the Cyprinids species, for example, can even grow up to 8 inches long and can live up to ten years in optimal waters. If you are interested in keeping a shark in a fish tank at home, you would require a little knowledge, but it is going to be very rewarding. Varieties range from rainbow sharks to silver Apollo sharks. The Apollo can also grow up to ten inches which is huge, as aquarium fish go. But Can you really keep freshwater aquarium sharks at home in a tank? The answer is yes. With a little care and management, everyone can enjoy keeping these sharks and experience their unique nature.
