The feeding of massivore was the only change that I did, and it was a very light feeding to see how they would take it. They all were healthy vibrant fish, no one was skiddish in the tank, they all swam around with the occasional chasing that didn't last more than a few seconds. I do not know what the cause was, but I want to explore every possibility of what caused it. Could have been with the w/c as we have experienced some rain this week so I do not know if that day the water dept had done something different over the time we got rain.....
