As the title says. I'm extremely disappointed as my derasa (purchased from Divers den) died yesterday. It was an awesome specimen. Probably my new favorite piece in the tank. Last Thursday it looked great. We went out of town Thursday and came back yesterday and when I got home it was closed up and I noticed my snails were trying to get inside. I knew right away he was probably a goner. This morning I looked in the tank and he was opened up and there was about 4 snails inside the shell eating his remains. This is my second dead clam. My last one was a small turquoise maxima that lasted about a week. I checked all my parameters when I got home yesterday and the only parameter I found off was my dKh dropped down to 7.0. I normally keep it around 9.5. Other than that, mg is 1420, ca is 410, and I dosed for alk. I did find a few pyramid snails (3 or 4) on it last night and I put it in a separate pail and brushed them off. Any suggestions on what to do? I love clams and really want to keep one. But I can't afford to keep taking losses and the old lady is getting ******. Lol
