Ive had a saulosi and auratus die on me in the past two days... No idea why. The auratus died first and then the next day the saulosi day. My water paremters are perfect and have not changed. The auratus was the bully of the tank and both fish were swimming and there wwere no known problems. All of my saulosi in my tank stick together and there never is or was that much bullying... Any reason why? Not trying to lose more saulosi....
