I have a pretty big ICK!!! factor when it comes to snails =/ Are there any other FW cleanup crew that will clean the substrate? I do weekly water changes but wouldn't mind having a little help with food the barbs miss and the loach+pleco ignore. The barbs are always at the middle/top of the tank and have their own spot to go chill/stare at the floor. After they feed at the top/middle, they completely ignore (or don't see) any food pellets or anything that might have sunk to the bottom.
