hondamx said:Why are you saying that bettas like small tanks. When I put my betta from it's little bitty cup to it's nice 5 gallon he was swimming around having fun. After a few days his colors looked soo nice. IMO 5 gallons is the min. tank size for a betta. It's not bad putting 2 betta in with a divider. It gives them another fish to look at. I've heard that if you keep a betta by itself with no fish anywhere or near a mirror it gets them depressed.

This is the number one betta site. It says you can put a betta in 1-5 gallons.
