My star fish is melting

[jason604]

i think what happened was it was stung by my tube anemone when i still had it about 2 months ago and it was slowly SLOWLY showing signs of damage. Anyways i just checked after coming home from work not too long ago and the weak looking leg has completely fallen off. is it gonerzzz for my starfish? i remember when i acclimated a different starfish a few months back its guts started to spill out the next day and it completed messed up my tank n corals were all going downhill... should i toss this guy out b4 that happens again?
