ideas 4 tank mates please help
i went and got myself a aquamarine colored betta. my niece named him swimmy. he seems lonely. he seems happy and swim+jump when i stick my finger in the tank. he is friendly, doesnt fight or bite. i cant put him with the others bcuz they will eat him. i have 2 buy the swimming fishes 2 eat. i cant put him the the small ones bcuz they r at my sis's shop and i dont want him 2 stay there. i have a 20 gal tank with lots of live plants and corals. i have snails and shrimps and frogs in there but i want him to have a fish friend. i dont want anything 2 nip him though. can u give me some advice?
