My German Blue Ram just died suddenly and I have no idea what might have caused it. At last night's feeding, he seemed perfectly normal. I did my regular WC this morning and again, he was acting perfectly normal. Less than 2 hours after the WC, I came in and found him lying on the bottom of the tank dead. All my water parameters are where they should be. No sudden changes in anything. All other tank mates appear perfectly normal. I know they aren't quite as hardy as some other fish in the hobby, but to see one die so suddenly is quite the puzzle.
Any ideas out there as to what could possibly cause this?
