I would say that the starfish is dying. I lost one of mine that way. Not sure exactly what killed it, thus I can't help you with that. All I can say is check the parameters like ammonia and nitrites. Some say high nitrates are bad for them aswell.surfnturf said:Please Help!
Hi, My choc. chip starfish looked fine this morning. This evening , a portion of one of his legs turned white & hard. What could this be? Can he be saved or helped?
