I noticed this about a week ago that my red betta has a big lump on his side and on the other side its only slight. I think its his stomach but only being fat on one side and barely the other?
I tried not feeding him for a few days and I think its going down slowly, can anyone help me?
My tank is 2.5 gallons, filtered, heated at 80 degrees.
I feed him 3-5 pellets of Aqueon betta food everyday except Sunday. Also every once in a while freeze dried bloodworms and Nutrafin Max.
He is still very active as usual and there is no sign of pain.
