So I added a clam to my tank yesterday and he looked fine. The mantle was full and the siphon and mouth were visible. Today it looks like it's hot happy. It is more closed up than I would like a new clam to be. Water paramaters are very good:Alk 10, Ca 420, temp 78, ph 8.1, no nitrates/nitrites
Should I be worried yet?
