Ok so we have had our clam for about 3 months. The other day he started acting funny. We would come in in the morning to turn on the lights and he would be open. His mantle is pulling away from his shell and his mouth is splitting larger. Water params are not great but he has been living in them for 3 months without a problem. They might not be great but they are constant LOL. Params as of now: Ph 8.0 Gh: 180 Kh: 120 No2: 0 No3: 40 we use strip tests which I know are not the best, but we some how always manage to mess up the other tests. I will get some pics of him and post them asap. In the mean time, does anyone have any ideas about what's going on?
