Hey guys, I noticed that my albino and endl are breathing hard and has some black string like things on there slime coat. The tank is full of bichirs. A few of them are breathing hard, only noticed 2 of them with the worms on it (i'm thinking there worms). Tank is a 120 gallon. Should I QT or treat the whole tank. I have coppersafe at home right now, is it going to work on these types of parasites? Or should I go with something else. Please let me know THANKS!!
