I have 2 upside down jellydown. I bought them at penny size, they grew to quater size.. then all of a sudden one went back to penny size and the other is half a penny... I do not notice a decrease in in tentacles or slower rate of pulsing (they pulse against the bottom once every second).

SG: 1.023

Feedings of marine snow half capful target fed each every 3 days. They are kept in a floating breeding container to keep seperate from my other fish (which my turbos always knock down..) I've had them for a month and they did nothing but grow until this past week.

Also for reference for you guys one stung me and it felt like a bee sting.. without the pain.. like you just felt that thumping, static feeling of a bee sting but it didn't hurt or anything.. but thats coming from a guy who walks bare foot and gets stung constantly and is used to it.

Okay, Id say a video is in order!
I have no experience with these and dont know anyone that has. could be a flow issue? could be salinity and pH! could be temp? was there any care info with them?
