Jellyfish Tank

[Enoplus]

This tank currently houses 3 upside down jellies and one lagoon jelly. The tank is a 20 long, I have a 2ft long t5 growlight for lighting as they contain zooxanthellae, and I have some sheets of glass for the light to rest on and to limit evaporation. The pump, filtermedia, and heater are separated by a piece of eggcrate, the pump is covered by a chunk of sponge to limit waterflow. I've also covered the sides in aluminum foil as to keep as much light in as possible, I don't know how useful this is. I feed them baby brine shrimp every day or so, but the upside down jellies can go a long time without food as long as they are well lit. AFAIK neither of these jellyfish require kreisels as upside down jellies sit on the bottom of the tank and lagoon jellies are strong enough to swim by themselves.

Neat tank. I will follow along as you document your progress. I'm possibly interested in something like this later on.

Fascinating!!!

You are clearly not a newbie with your setup, but welcome to R2R anyways!!!

One of my favorite places on Earth is a spot in the Florida Keys where tens of thousands of these things, in about eight different colors, live and make this large area look like an amazing flower garden. I hope to be able to make a simulation of it in a big tank someday. These little guys are just adorable.

Awesome! How difficult are they to keep?

Also 400w heater seems scary in a 20L tank, what's up with that?

They've been pretty easy to keep so far, I think anyone with basic saltwater aquarium knowledge could keep upside down or lagoon jellyfish. The most important things to keep in mind are to make sure they can't get sucked into any pumps and to keep the flow fairly low. Regarding the heater, it was the cheapest one with the best reviews on amazon, in my experience its a really nice heater and I'm not worried about it.
