Omni 9 gallon Jellyfish Aquarium

Regular price $260.00 Sale


Omni is a latin word that means “all”. At the Jellyfish Warehouse, our goal has always been to offer rare and previously unobtainable jellyfish to the public. As jellyfish hobbyists ourselves, we wanted a place where anyone could get jellyfish or aquariums. That’s precisely why we created the Omni tank. This aquarium combines functionality with design, while also being the most affordable option on the market. Right out of the box, you will be set up for success with keeping a wide range of jellyfish. 

We took the wildly popular Fluval Flex Series Aquariums and modified them with a new exit diffuser and spray bar manifold to provide the proper environment for your jellyfish. Fluval stands out as one of the leading aquarium manufacturers in the world, and was an obvious choice to supply the glass for our jellyfish tanks. Speaking of which- this is the only jellyfish tank on the market made of glass. Plastic is easier to form and bend but we wanted something sturdy and scratch resistant that would last you a lifetime. 

Complete three stage filtration is built into the back compartment of the tank. Water trickles over a filter pad and then a bag of our SuperStart biological media. This means your pH will be stable and your tank will never have issues with ammonia. 

At 9 gallons, this tank is the appropriate size to keep most jellyfish species. As a complete kit, you simply just add water, and turn it on. For those with experience and looking to branch out, there is room to add an external canister filter, heater or chiller and much more. A perfect option for both jellyfish beginners and experts.

Moon Jellyfish 

Upside Down Jellyfish 

Lagoon Jellyfish

Flame Jellyfish 

Ice Jellyfish 

Fried Egg Jellyfish
