i'm looking after my dad's tank while he's out of town and i think one of his sea anemone is dying! it's all shrunken and looks altogether miserable..

Yep its desintegrating, definetly take it out, I will advise to smell before taking it out, because if its not smelly, its prob not dead

Yeah, pull him out and smell him. If he smells like nice sea air, then he's got a shot. Otherwise, don't put him back in.
What happened to him, anyhow?
