Upside Down Jellyfish

I just got one two days ago and I love it, this is the coolest thing since my yellow watchman goby joined my tank. Does anyone have a Upside Down Jellyfish? Let me know how big they get and what special needs that it might require, I had to get rid of my pink tipped anenome but I was looking for an excuse to deport him! I was even thinking about adding a second jelly to my 75g next week, let me know what you guys think. I have attached a picture for your enjoyment!

 

Awesome. Cool to see jellys working there way into the hobby more.

 

Have you had any issues with them?

I have been trying to research... so they are like nems?
If one gets in a powerhead will it nuke the tank?

Very neat creature.. and diifferent.. which is what I like in my tank

 

We have a whole tank of those at the Tennessee Aquarium. The only real problems I know of are that they need to be flipped back "upside down" when they flip over, because their food comes from the algae they grow on their "underside" (top?). In other words, you don't want to have a right side up upside down jellyfish.

 

Why would you want to get rid of an anemone but get that? They have just as specialized care and all the risks.
They require very low flow, bright lighting, and constant phyto feedings. The fact that its moving around like in the pic leads me to think that it is not happy. When happy it should be on the substrate rarely moving.

 

So these will or wont nuke the tank?
Would like to have one just because it is very different

 

Yes, they potentially can. Even with a low power sting, if it were to get caught in a powerhead or such, it can potentially pump a lot of its toxins into the aquarium and cause damage.
They really should be in a species tank, as a community reef tank with all its flow and other inhabitants is not a very good place for them.
Adult size is about 8" in diameter.

 

So same dangers as a nem them.. Except these are more mobile...
Hmm.. How is yours doing nightstick?

 

So far so good, he did need to adjust to the tanks flow though. It now know where he can and can not swim! I got rid of the pink tip nem because he was getting to large and killing everything he touched, not to mention he was moving alot. The jelly is now enjoying the substrate and seems to be doing fine. I dose alot of phyto so that was no big deal. I was thinking about getting another since they aren't very common.

 

I had one....I got rid of it. It was in its own tank. Requires very low to nonexistant flow and are really not safe in a reef tank..anything it stings will probably kill it!

They are easy to keep if you know how to care for them. They require daily phyto feedings (target) and exact salinity readings...they are like 98% water and will not tolerate the slightest SG change.

They should not really move...if it is it is because it is getting caught in the flow of the tank. Otherwise it usually sits on the bottom of the sand wtih the tentacles up.

I would never think of putting one in my reef tank I had mine for 3 months and was doing well....but it was not worth the work I had to do to keep it alive...so I sold it to the LFS who sold it to somebody who had no idea what to do iwth it and killed it in a week
