I love my betta to. I have a 20 gallon long with 1 male betta, 3 mollies, 3 platys, 1 fancy guppy, two ottos and 1 snail that hitched a ride with the live plants I bought. In the tank I have some caves, driftwood and some small swordtail plants that they leave alone. They all get along great. The betta was so happy when I took him out of the tiny cup he was in and put him in the tank. Now he explores and plays all day. There is no fighting at all..
