Whats the Difference Between a Fighting Conch and a Queen Conch?
Fighting conchs (Strombus alatus) have white and brown shells. Since fighting conchs eat brown diatoms and other algae on the surface of live sand beds, they stir and clean upper layers. Queen conchs, Strombus gigas, have gray shells and are algae eaters. They graze algae on live rock and even off the glass. They will also consume detritus on the sand bed.
