The Nassarius Snail is a little snail with a big appetite. This hungry critter glides through your aquarium foraging for food. The Nassarius Snail is an efficient scavenger and detritus eater and is the perfect member of your reef aquarium cleanup crew. You will be pleased at how quickly a small group of Nassarius Snails will clear detritus, uneaten food, decaying organics, and fish waste.
Greech, honestly I think 4 of plenty for a 40G. Nassarius snails can do damage to a sandbed by eating too much of the infauna. Nas snails are carnivores. With them, a little goes a long way. Cerith snails on the other hand, you need a couple dozen to keep diatoms in check in some tanks.
