Conch

[canadawest]

Apparently they (fighting conch's in particular) have an excellent reputation for keeping the sandbed clean. They apparently have an appetite for detritus, diatoms and slime algae. I have two in my tank for diversity, but also to test their cleaning ability.

Not sure if mine are fighting conchs or another type, but they are a cool addition.

I believe Seacare has some left.
