Yellow Sebae question

[BrokenReefer]

I bought one a week ago, it's doing just fine or so I think.

It has not found a place to rest. It just floats around the tank with it's disc blown like a baloon. Is this normal? What do they normally like for substrate? I wonder if there's something I can do to help it out or if it's just doing it's thing.

Thanks.

Its not normal at all. The mouth is inflated which is a sign of stress.

It prefers sand.

What kind of lighting do you have over your tank? What are your waterparameters? Did you acclimate the anemone? Was it in good condition to begin with? Is its mouth gagging open?
