A few weeks ago my boyfriend noticed white spots around the mouth of his featherfin cat. Posted pictures and most of the responses agreed that it was probably ich. So we added a very small amount of aquarium salt to the tank and cranked up the heat (heater on full blast, the water temp stays around 86). Unfortunately, the little guy still has the white spots around his mouth so we're starting to doubt that it's ich. His interest in food wasn't very consistent before this but it doesn't seem to have changed much, and he doesn't act unusually lethargic or agitated. Also, none of the other fish have developed these white spots and there has been no other illness in this tank for over 8 months.
The only changes made to the tank in the last two months were the addition of a small powerhead and two bleheri plants from my tank, which hasn't seen any kind of problem like this. Water parameters are good (ammonia & nitrite = 0, nitrate = 20+) and the tank has sand substrate. Since noticing the white spots, he's stepped up the water changes.
So, any ideas on what this is? Neither of us have a clue, but because none of the other fish have the spots and those on the featherfin don't seem to have improved or worsened, it doesn't seem like ich.
