Jellyfish Tanks

Jellyfish are one of the most fascinating creatures in the oceans of the world. They inhabit all the seas and oceans across the world. They live right up at the surface and at the very depths of marine waters. There are more than 2000 known species of jellyfish and some of them are even found in freshwater. They have existed on planet earth since further back than the dinosaurs. Most people have heard about jellyfish stings, but the fact is that on humans, most jellyfish stings only have the impact of minor discomfort. Some species, however, may be dangerous to humans and these are usually found in tropical and temperate waters.

There was a time when keeping jellyfish in tanks was considered the domain of public aquariums and scientific communities alone. This is because it is extremely difficult to maintain creatures as fragile as jellyfish in captivity. However, in the recent past, more advanced technologies in jellyfish tanks have made it possible for hobbyists to keep jellyfish as well. Also, sale of jellyfish is prohibited to public aquariums and since they were the only keepers of jellyfish, it was not possible to acquire jellyfish. In the recent past, however, private entrepreneurs have entered the market and made it possible for us to purchase jellyfish.

Jellyfish can be kept alive in captivity under very specific conditions. Since jellyfish are physically delicate, their needs are very specific. Jellyfish tend to flow with the current and they are suspended by the current. Their tank has to be specially designed to replicate their natural environment. The water supply has to be managed in a way that provides current to the water in the tank but the current should not be strong enough to suck the jellyfish in the water inlet. The water needs to flow through a screen outlet in a way that provides a gentle swirl to the water and keeps the jellyfish suspended, without disturbing the equilibrium of the jellyfish.

Jellyfish tanks require filtration similar to coral reef tanks. The filtration system should have the ability to skim the surface. It should also provide mechanical and chemical filtration. A biological filter also needs to be in place for the filtration system to provide a thorough filtration of the jellyfish tank. Some experts are of the opinion that a jellyfish tank would also benefit from a protein skimmer in the filtration system. In nature, jellyfish are known to inhabit waters which range from 55 to 65 degrees. This means that a jellyfish tank should be able to replicate and maintain this temperature. For this, a refrigeration unit or a chiller is required.

Finally, with a jellyfish tank, the question of what to feed the jellyfish also arises. In nature, jellyfish mostly feed on live plankton. There are no real sources of live plankton available to us. While these are being developed, the closest available substitute is brine shrimp and jellyfish older than about 10 weeks can be fed brine shrimps. If the jellyfish is younger than 10 weeks, it is usually fed rotifiers.
