Hey all. I would like some advice here please. I have recently switched tanks, and in my old "matured" tank, I had a medium crocea clam that was doing well. When I first transferred it to my new tank it did well for about 3 days and has since been completely retracted with signs of pinched mantle disease. I gave it a little more light as it was reaching a little in my old tank. Water parameters are good, pH maybe a little low: pH 7.9-8.15, Alk 9, Cal 500, nitrate 5ppm. This is pretty close to what I kept it at in my old tank except nitrates were around 1. No pyramid snails. If it seems that my tank is too new I would be open to DBTC'ing this to someone who can save it, or is there something I can do to fix it first?
