I have two males at the moment. Both are in 5.5g tanks with filters and aquatic bamboo and some other plant I can't remember the name of. Lots of cloth and plastic plants for hiding.
Would be getting either of them a fish to 'keep company' be a good idea or not? If so, what? Something preferably low maintenance.
I've tried snails before, hate them. They're messy and gross. Had a cory cat back when I had a sorority but I thought he was getting too big and his wafers made a mess then the girls would eat them.
