Male HM. Was constipated and bloated 3 wks ago. Treated w/ Epsom salt and changed diet.... He recovered, but started tail biting. Was active until today.
Today: Caudal and anal fin gone almost to the body. He was not like this yesterday!
(Dorsal, ventral, pectorals are OK.) Bits of fins were all over the bottom of his tank. Lethargic, and does a slow float up/sink down. Treated w/ 100% WC and 1/4 tsp Epsom salt.
Mainly worried about his fins! (See pics.) Are they OK?
