So I recently got a male betta, his name is Gromit, and I am looking to see if there are any other fish I can put in with him. It isn't a huge tank so I am just looking for one or two other fish. I have a small filter in already, and I know Bettas don't necessarily need filters. Are there any fish similar to bettas, that dont need filters? Also, what kind of food would I feed the fish, if they are different types?
Thanks so much!
