Yea, certh and nerite snails are known for being inter-tidal snails, so they'll stay at the top of the tank, and occasionally climb entirely out of the tank. Eff that noise, astrea and turbo snails for me. I don't need the trouble of snails getting into my overflows and plumbing and stuff.
I keep a close eye on them, or I try to anyway. They have done a real good job of controlling my diatoms and other minor algae outbreak. Astrea and Turbo are next on my list! Thanks for the suggestion!
