bloated starfish? What do I do?

[michika]

I've had it for two months, and I haven't seen anything happen to it.

I just don't see how it could overeat and bloat in three hours. I'm just so confused and unsure of what to do for it.

Its started to deflate, but it still puffy around its disk. I'm concerned about putting it back into my display tank at this time because right now it is QT by itself in a very very empty container (e.g. the starfish, an airstone, and a thermometer). I have other things in my QT tank at this time so I'm not willing to put the starfish in with $200 worth of fish...

Ideas on what to do?
