i bought some discus about 2 weeks ago. Well they were a sick batch to say the least. We bought 5 and 2 remain. I treated one that we have left with a salt bath and have been running warmer temperatures for the past couple of days and it seems to be working. One of them is fine, absolutely great. The one i gave the salt bath to, his side is better (had discoloration) and he's eating but he's still almost black. What I was wondering is will he get normal coloring back if he lives? They were supposed to be blue tourqs and the healthy ones (we have others) are nothing like him.
