Conch does laps around tank?

[bbgobie]

My strawberry conch mostly follows the glass and goes around my tank. I get these perfect 90 degree corners and about an inch of nice clean sand along the glass. Is he ever going to find the stuff in the rest of the tank? He can turn around. I've seen it go both directions and sometimes venture away from the glass. But as soon as I get excited a few minutes later he's back cleaning his track around my tank

Everyone is a Lazy eater, my Trochus Snail do an excellent job cleaning the Back Black glass, which has plenty of algae on it. Also my Yellow Watchmen Follow whichever glass scrubber around and follow the Baster around to get the Pods.
