My two convicts have laid eggs and the female appears to have one white spot on her tail and one white spot on her dorsal fin. They aren’t what I normally think of as ich (lots of small white spots covering the fish). It’s only two fairly large spots that she has and she’s the only fish in the tank with it. The male doesn't, the red tail shark doesn’t and neither does the spanner barb in there. Nothing new has been added recently so I’m not sure.
