I have a ten gallon aquarium with a Betta, two African Dwarf Frogs, and a Nerite Snail. I have tried feeding the frogs freeze dried foods, peas, and pellets, but all they will eat is frozen bloodworms. When I put the other foods in, they look like they can smell it and want it, but they won't eat it. The food can be right in front of their faces and they still won't touch it. Is this o.k. or should they have more variety? Do you think if I tried different kinds of frozen foods they would eat more?
