I've had my beta for about 3 days now and he wont eat. He wont eat pieces of shrimp pellet, floating fish food, and wont eat Wardley Betta pellets either. Only thing he'll eat is when i find small bugs in the house i put it in the tank and he looks at it for a long time and then eats them. His betta food he spits back out. Should I just starve him a couple of days and try again?
