We have a female beta. She is in a 2.5 gal tank with a snail. We are setting up a 10 gal. and would like to get her a friend or 2. Would a paradise fish be a good tank mate? Since they are both labyrinth fish and close to the same size.
Bettas should never be put together with any labyrinth fish. They will fight! A good tankmate for her would be a couple of otos or cories. They will also help keep the tank clean of algae. Females can be very aggressive (at least mine are) and I wouldn't trust them with any fish that swims at the same level as them. Otos and cories stay near the bottom and are no threat to her.
