one betta in 5g hex tank, need tankmate
So i have one betta in a heated and filtered 5 gallon hex tank, and thats it. I realize this is a great space for a betta and am really not looking to add more fish, I really just want something that is usually good with a betta and will clean up excess food in th gravel, or algae if it gets any. I obviously don't want soemthing that gets big like a pleco or something, and I was interested in getting a apple snail but the guy at the pet store said they don't do good with heaters? Ideas?
