We recently moved my daughter's betta from his 2 gallon bowl into her ten gallon community tank. So far, things are great, he is more active and seem much happier...he used to just lay around in his bowl. However, I cannot keep him from eating the tropical flakes that we feed the other fish in the tank. I am able to feed him his pellets fine, without the other fish stealing him, and I feed him first, but then when we put the flakes in, he also eats those along with everyone else. I'm afraid he is going to get overfed. What should I do? He loves the flakes, can we just switch him to those, or does he need actual betta food? What if we switched them all to a tropical fish pellet? (If flakes are bad...?) Thanks!
