How to tell if nassairus is healthy?
I introduced a 1" nassarius snail to my 10 G tank last week. It's the only sand sifting animal in there. Only once have I seen it surfaced, all other times I only see the tip of his siphon in the sand, which changes location every few days. How do I tell if it's healthy and feeding properly? Should I supplement its feeding? With what?
