Hi everyone. I currently have my betta in a 3.5 gallon tank and I was wondering if it is big enough for any other fish to be added. I want to get a bigger tank but my boyfriend doesn't want anything bigger in our apartment so for now I'm stuck with the 3.5 gallon. I feel like my betta might enjoy the company so I wanted to get a few friends for him but I don't want to crowd the tank. Any ideas or suggestions? Or should I just wait til I can have a bigger tank?
