I have had these guys (four total) for at least 3 months now. Recently about a week one of them started exhibiting clamped fin in the tail (I did not know what was happening). And couple days ago, another started exhibiting the same.I have not noticed any signs of ich (white spots) or velvet (rust like) so I guess it is stress?Everybody else seems to be doing okay, crystal shrimps, guppies, badis, celestial danio... I checked the water (API liquid test kit) and params seem within normal ranges. Have not introduced anything new to the tank. The water quality is very clear, not cloudy at all. I cleaned the canister filter yesterday and it was dirty.Has this happened to everyone else and what did you do to help your fish?
PS. Should I try using API Stress Coat+, Melafix or Aquarium Salt?
Thanks,
