This may seem a little strange, but I'm thinking I just watched my ram choke to death. Was doing my nightly feeding. This time I fed a cube of frozen brine shrimp. Everyone looked good, feeding well, but as they were finishing up feeding one of my (new) German Blue Rams started thrashing wildly and within minutes was dead. It had looked fine all along and was eating well, and then it was all over. Sitting by the tank right now and everyone else seems fine. Thoughts?
