I just moved my second baby channa maru into a new aquarium.75 gallon aquarium I think? (We don't really use gallon in my place)Just one day after being moved,the fish fin is bleeding and rotting including decoloration.I suspect that it is fin rot but I never face bleeding fin.My another channa maru placed in separate tanks is doing great.Someone please help me... I also attach pictures of my healthy channa maru compare to the one that is sick
