So, I've had this betta for about 4 months now, and just had to move him out of his community aquarium because HE was being picked on! So, now I'm going to set up his own small tank for him, and the LFS guy told me I could put a few small fish in there with him. Any suggestions? I'm not sure how big it will be. Probably atleast 5 gal. Oh, and it won't have a heater, but the temperature shouldn't drop below 70. Post picts. if you can!
