The Tiger Sand Conch, Strombus sp., is an extremely capable scavenger that works hard to clean aquariums of algae and detritus. The Tiger Sand Conch will spend much of its time burrowed under a sandy substrate using its siphon to search for food - thus they should be kept in tanks with a think sand bed as well as plenty of live rock. Sometimes, hermit crabs can pose a threat to the Conch by trying to steal its shell - it can be wise, if desired to keep with hermits, to include some empty shells to reduce competition. The Tiger Sand Conch is a very peaceful species and will only ultimately be beneficial to your tank.
