My P. Endli Endli got beat up by my P. Endli Congicus. This is my favorite fish, and now her tail fin is shredded. Some of it turned white, some of it turned red, some of it is gone. She typically relaxes all of her fins when she isn't swimming, but she's keeping everything erect and appears to be in pain. I'm going to start Melafix treatment ASAP, and raise water temp. I know it's also recommended to add salt to the water, but how much should I add for a 55g? If this was any other bichir, I wouldn't worry... but Indy's my baby
