I recently got a Queen Angelfish and she appears to have Lymph from what I can tell. It was only on her right fin but now has it on her pelvic fin and her tail fin. Nothing on her body. I've never dealt with Lymph before. I am dosing copper in the tank currently because I had an ich outbreak. It is a dedicated FOWLR tank and I have been using cupramine, levels have been at therapeutic for almost 2 weeks now and I have not seen any ich in over a week. My main question is: does lymph cause fin damage? Because the fish's fins look almost like fin rot on the tail fin and pectoral fins. From my research there isn't really anything that I can do for the lymph other then make sure she's fed well with vitamins and the water quality is on par. My current parameters are as follows (all using Red Sea testing): NO2 - 0, NO3 - 0, PO4 - 0.06, Salinity - 1.023, NH4 - 0, Temp - 78, pH - 8.2. I does Kanaplex via broadcast in the tank every two days for six days as the instructions stated. Going to start dosing in the food if need be with Focus incase it's a bacterial infection. No other fish show any sign of this illness and are all eating well. The queen eats like a champ, begs for food when it's feeding time, is very active and doesn't seem to have labored breathing. I've only had her for a week and a half but I don't want to loose her either. For tank mates there are: 6 Blue/Green Chromis, 1 yellow dwarf angel, 1 Orchid Dottyback, 1 Phantom Clown, 1 Diamond Goby. There has been no aggression from any of the fish at all and they all seem to cohabitate very well. I have attached some pictures of the issue. She's not very photogenic so they are the best I could get lol. But if you guys have any thoughts or recommendations on how to treat this I would greatly appreciate it.
