I have had this Black T max for about a year. I bought it from Karl (Unarce). He had it for a while before I got it. It has been growing and doing super great. Then about two weeks ago it started to look funky at the two corners where the shell meets, pulling in its mantle in the corners but extended in the middle. I have been watching it and it seemed to open more here and there but the corners seemed pulled in. Today it seems more pronounced so I snapped a quick picture and thought I would ask what you all think it could be. I have not found any Pyram snails. No new clam additions, this is the only clam in the tank. Params are stable, alk 8.0, cal 435, mag 1250, Ph 7.8-8.2. I am super bummed as I feel like it may be going south on me very slowly. Can I do anything to save it?? Dips?? treatments?? I am clueless as to what could suddenly be bothering it. I have not seen any of my fish touch it at all.
