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.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?
