Ok i am treating for ICH with my clown loaches, question is when the white spots fall off or disappear will it or could it leave scars on the fish? My loaches seem to be free of the spots but their fins still have what appears to be scars where spots were. They are both active now and very playful so stress seems to be gone and the spots have been gone for two-three days now, will keep up salt till this sunday then back off treatments per schedule i am following.
