Buying and Installing Your Aquarium

Buying a jellyfish tank is considerably more complicated than purchasing a tank for regular fish. The aquarium you choose will need to provide a constant flow of water that mimics the flow of the ocean so that your fish can stay suspended and will not come into contact with walls, filters, and the like. There are a number of different types of tanks available, and here we will take a look at some of the most popular ones as well as how to set them up so that they are ready for your fish. We will also look at where to place your tank as well as how to set up the lighting and create the ideal water composition and temperature.

Tank Types

There are numerous different types of jellyfish tanks. Each offers a different layout and design as well as different benefits and mechanics. By and far the most ideal home for a captive jellyfish is in a kreisel tank, but there are many different types of aquariums that are well suited for jellyfish.


This shape works well for jellyfish (see public aquariums, Jellyfish Art's Monaco tank and the new cylindrical desktop tank from Jellyfish Art). The water flow mushrooms out at the top and flows down the sides, which sweeps the jellies up off the bottom. Works very well for moon jellies, not well for sea nettles unless it is a huge cylinder.

Kreisel Tanks

A kreisel tank is a circular style aquarium that is designed specifically for jellyfish and other delicate aquatic creatures. These tanks have no corners, which reduces the risk of injury to the animals. The water flows through the tank in a circular motion, and water flows both in and out to provide suspension. These tanks have small screens that keep the suction from harming or catching the jellyfish. Because these tanks are so costly and nearly impossible to purchase for home use, there are a number of other tanks that are sold for home jellyfish owners.


Jelliquariums are designed for use in a home or office space and are well designed for maintaining jellyfish. The price of these tanks can range anywhere from a few thousand dollars to ten thousand dollars or more. They are very stylish, however, and are entirely safe for jellyfish. They come in a number of sizes and styles, ranging from entirely opaque to enclosed on three sides in wood or other materials. A Jelliquarium uses a skimming surface and an anti-siphon design that helps keep water flowing properly without risking the jellies being caught in suction. The lack of corners in these tanks also helps to keep fish safer.

There are numerous types of Jelliquariums. While many are freestanding floor tanks, there are also some that can be mounted directly into a wall. The design of the tank allows for easy maintenance. Most tanks also come with lighting that is designed to ensure that your jellyfish glow and provide a beautiful touch to any space.

It is possible to purchase smaller Jelliquariums that are rectangular in shape. These smaller tanks are far less costly, but are mainly used for studying the fish and for breeding them. They are only a couple of feet wide, but offer a water circulation pattern that will help keep the jellies suspended. These tanks are designed to be passive, meaning that they must be hooked up to separate water inputs and outputs, and are usually used as part of a larger system.
