Well, after I checked that bag my banana plant came in last week and found a snail shell, I was kinda afraid I might have more hitchikers... and about 5 minutes ago I just found the first one crawling on the front of my aquarium (inside, obviously). So, I know clown loaches usually make quick work of snails, but should I take a scraper and knock it off onto the gravel, or will one of my clowns find him where he is a few inches off the bottom?
