As ATM has pointed out, it could be the Neon Tetra Disease. It could be something else as well. Are the fish eating normally? Is their coloration normal, or are they pale? Do you see any swelling anywhere on their bodies? Do they swim with balance or are they swimming on one side? Any growths (like salt-like grains or cottony-growths) on their bodies?ado said:hi all

but they do swim properly for a bit
