The nice thing about these frogs is that you can put as many as you like together, and they don't get big. Yours is full grown!!. They come from Asia where they live in the rice fields.lol You can put them with the dwarf ACF. They will eat guppies,bloodworms,blackworms,tubefex worms, yummy. Thats a nice all around uncommon frog. Whats his name?
