Breathing new life into an old thread... Thought I'd hire a clean up crew for a 10 G that is getting over run with cyano and some green algae. The LFS had Astrea and Turbo. I got three Turbo. They are like aquarium Roombas! Seems like everyone likes Trochus. I like the fact they reproduce. Are there any snails I should avoid with a acrylic tank? Would you consider them a carrier of any diseases and QT them?
