Try this! It's what works for me
Buy a 5.5 gallon tank, it's very cheap. Buy 2 dwarf frogs and a dwarf pleco, let them settle in for a week or two. the first few days they will be less active because they should be adjusting to the environment. Dwarf frogs are bottom feaders, but like bettas they require swimming to the surface to get oxygen. My frogs eat the food that floats to the bottom after feeding my betta. When I feed them pellets every now and then; they have to be target fed. The reason for a smaller tank is because the dwarf frogs actually are not the best swimmers, and it is a struggle for them to swim upward for more then 20 in. The smaller the tank, the easier it is on the frogs. When there is many other fish, they swim to the top less frequently; therefor, less oxygen.I added a betta in with them and things have been great.
