We have a Biocube 14. It has been set up for about a year with live rock and sand from a 3yr old tank. We put a clown and recently a green BTA from my dad's tank (wasn't happy in there, we thought because of my dads other anemone). It has been settling in fine. Then the other night it was swimming around the tank. It has been wanting to hide when the daylights come on. Then I get home from work and it's all shriveled upside down like this. Is it dead/dying?
