Want a Living Lava Lamp? Starting Your Own Jellyfish Aquarium

A while ago, I went to a public aquarium. They had all kinds of fish (as you’d expect), but by far my favorite exhibit was the jellyfish tank. It was tucked away in its own little corner of the aquarium, closed off from the hustle and bustle of the popular shark exhibit and petting tank. The room was completely dark, save for the built-in illumination within the jellyfish tank. The tank itself was a column-shaped pillar that spanned from the floor to the ceiling. It must’ve been about five feet across and eight or nine feet high. Inside of it were dozens — possibly even hundreds — of jellyfish. The built-in light slowly shifted through the spectrum of the rainbow to illuminate the translucent, ghost-like creatures. All put together, it was incredibly peaceful. A semicircular bench allowed guests to sit and watch the jellyfish, and that’s all people were doing. The room was practically silent except for the subtle music playing in the background. Wouldn’t it be nice to have this kind of peace in your own home?

Luckily, you can. Jellyfish aquariums are a great alternative to conventional fish aquariums because of the unique shapes and movement patterns of jellyfish.

Benefits of a Jellyfish Aquarium

All aquariums are peaceful, but there’s just something unique about jellyfish aquariums. They have their own special brand of serenity that you can’t get from other aquariums. Why is that? Well, it’s kind of hard to say. A typical aquarium is kind of like the visual equivalent of putting your feet up and relaxing on a tropical beach. The scene is beautiful, so you feel relaxed. Jellyfish aquariums, on the other hand, chill people out because of the gentle movements of the jellies. These aquariums are peaceful in the same way that listening to wind chimes is peaceful, or like watching a fire crackle away in the fireplace on a frigid winter night. The movements are hypnotic, they draw you in completely, and before you realize it you’ve been staring at the scene for five minutes without thinking or saying a single thing.

Restrictions of a Jellyfish Aquarium

You can easily replicate that same sense of peace and tranquility in your own home, but the only catch is that jellyfish aquariums have some unique requirements. First of all, you can’t really put anything else in the aquarium with your jellyfish. The jellyfish will kill any fish, and there’s a fairly high chance that their tentacles will get tangled up in plant life.

The other issue with jellyfish aquariums has to do with the current. Jellyfish aren’t able to swim against the current, so if you include a standard water pump in your aquarium it’s only a matter of time before your jellies get sucked up the tube. You have to use specialized water pumps in jellyfish aquariums. For the same reason, most jellyfish tanks are circular. The unique shape cuts down on the number of corners where jellies can get stuck.

Fun with Lighting

Your aquarium will be truly eye-catching if you install an LED light system. The bodies of the jellyfish will become whatever color you shine on them, from warm reds to cool blues. This is a great choice for night clubs, bars, or restaurants. Change the lights on the LED to fit the music for a stunning display that’s sure to excite your customers.

    Don’t molla mollas (a type of fish) eat jelly fish, how about whale sharks. My betta also eats them. He simply just grabs the tentacle free part of the jelly fish using his mouth and then holds then toss my jelly fish on top of his water lily and waits for it to die, then, as soon as it dies the betta has a feast.

    One consideration not mentioned here is that most Jellies have a very short life span. Generally months rather than years.
