I have a 7/8 year old Parrot fish that has just recently developed a reddish lump on the side of it's face.
The aquarium parameters are al within the acceptable range.
The aquarium is approx 300 gallons and is set up with a continious water chage system.
I have moved the fish into a hospital tank and applied General Cure for now.
I am attaching a pic of the lump. Is this something that is curable?
