Can I put a school of cardinal tetras with my betta?

I have a planted ten gallon with a betta fish, and I've heard that cardinal tetras could make good tank mates for bettas. I've never kept a betta with other fish and I'm, just not sure if I should risk it. I'm also not sure if ten gallons is enough room for a happy school. Should I just get another tank? Any oppinions?

You could, but I agree that 10g is a little too close for comfort. Some bettas can get a little stressed with active schooling fish. I have a betta in a planted 10g with 6 pygmy cories and they've learned to live together with no injuries, only a little chasing at the beginning, but I can't help but think that the cories would be happier and more active in a larger tank.

If I could re-do my betta tank, I'd just do nerite and ramshorn snails with him, but I love snails.

I think it depends on the general disposition of your beta. I keep 7 neon tetra with my beta. When I first introduced the neon tetra, I set aside a few hours where I could be right by the tank observing his reaction and ready to rescue the tetra if needed. At first, my beta followed them around the tank, he was curious about them. After a little time, the beta and the neons kind of went their separate ways in the tank. Now they seem to occupy different levels of the tank primarily. I feed the beta first at feeding time, and that gets the neons all excited to eat, therefore less of their slow sinking pellets go to the bottom of the tank. Good luck with your fish keeping adventures!
