My brother has a 5 gallon mini-bow tank with one male betta. He does consistant water changes, however, algae still seems to build up sometimes more than other times. Is there anything that you guys recommend that he could put into this tank to eat the algae. I was thinking Otto Cat, Golden Algae eaters. Don't know what will work with the Betta. I don't want the Betta killing anything or vica versa. Also, I want to make sure they will get along. Keep in mind it's a 5 gallon tank. Please, any suggestions would be greatly appreciated.
