In the aquarium, the so called "cleaning crew" refers to those invertebrates that keep the reef tank clean by eating leftovers and algae. It consists mainly of hermits and snails, which eat algae and sand snails, which circulate and clean the sand bed. A sufficient stocking with these animals is an important prophylaxis against algae growth. We offer useful compilations of invertebrates that cover the needs of the most common tank sizes.
Hermit and snails can be safely used as a cleaning crew in your aquarium, as soon as you notice algae growth in the start up period - normally this is around the second week after setting your tank up. With strong algae growth up to 1 algae-eating snail and 1 hermit crab can be calculated on 10l tank.
