Hey everyone. Heading in to my LFS today to pick up 2 male 4 female Multies today. There going into a 20g long, and I'm curious what kind of tank mates would do well with them. Mainly concerned about bottom feeders/scavengers. I know cories are harmless, but I'm afraid of them poking too close around the Multies' shells. Would a few mystery snails do well?
