My sister has a beta fish in a two gallon tank with a filter. He is about two years old. The tank belonged to my fish until he died (almost 4 1/2 years old when he died) we cleaned the tank out and put her fish in it. He was fine for two months but then he starting swimming oddly. I woke up this morning to feed him and his pupil is white.
What is it and what can I do?
