Hmmmm... Bacterial bloom maybe. I had an issue once (and still time to time) where I get big bacteria blooms that leave films on the glass and kind of stringt, bubble things coming off the rocks (not dinos), and they seem to flourish during daylight hours. When this happens really bad I find everything looks unhappy. My theory is that the blooms drop the O2 levels in the tank (this has been scientifically proven for many bacterial blooms) and everything suffers. I think this is ultimately what caused my cantaloupe sized birdsnest to crash. Took me forever to figure it our but once I got the bloom under control everything bounced back and stopped dying.
