I need some help identifying these marks on my PB. I lost another PB the same size and trying to bring a 18" arowana out of a sickness in hospital tank. These fish were all on feeder fish. I have since quit feeding feeders. Trying to get this one to switch to silversides and kreel but to now go yet. Its been about a week since she has last ate. I have treated my 150g with prazipro so far and its on day 5. I have a new FX5 waiting to be set up but I need to know what these spots are and if I can use another medication to treat before setting up the new filter.
All other fish in tank seem to be just fine. 2 clown knives, 2 pike cichlids, 2 silver dollars, 2 tin foil barb, 3 catfish. Knives and pike cichlids ate the feeders all the time as well.
Any help or ideas would be greatly appreciated.
