Also, he needs a five gallon tank. What are the parameters and temp of his current set up?
I would argue the fact that a betta NEEDS a five gallon tank as ive raised many to three years of age in one gallon bowls when i was younger, but yes, 5 gallons w/filtration and heater is the ideal setup providing optimal conditions, longer lifespan and minimal stress for a betta which causes things like this to happen.
A picture would be helpful. Sounds like some kind of fungus
