SO the guy at the fish store said that a good tank mate for my bettas that would clean the bottom of the tank would be the small catfish. He said they like to be in pairs but do just fine on their own and it would be fine getting one for each section of my 10 gallon tank divided three ways and they would clean the gravel much better than ghost shrimp would. What do you think?
He also said it'd be okay if I wanted to put one guppy or one platy in there with each betta but I wasn't too sure about that. (Not in addition to the catfish)
