a few nights ago, i did a water change, maybe a 15% one. the next day when i got home from work, noticed that one of my derasa clams had died, only shell left. clam was only 3 -3.5 inches. my tank is a 125 +30ish gallons of water in the sump. since, i have had several zoas not opening and green brain acting funny. i have done a couple 10 gallon water changes since but things still havent opened. all my parameters check out OK including nitrates. any thoughts? are there toxins that could still be in the water from the clam dying. also as a note, i have 2 other similar size derasa clams in the tank and they look fine.
any ideas apprecciated
