Olive Sandsifting Periscope Snail
The Olive Sandsifting Periscope Snail is a little guy with a big appetite for detritus. Add a group of them to the aquarium and watch for their periscope poking out of the sand while they eat fish waste, detritus, and uneaten foods. Their shell has a striking resemblance to the highly venomous Cone Snail, but don't worry because the Olive Snail is not dangerous to fish or their aquarists. Do not be too concerned if you do not see this snail all the time because they like to burrow into the sand in search of food. When they burrow into the sand it has the added benefit of turning and aerating your substrate. Since they are known to nibble on other invertebrates, this snail is not considered reef safe. They prefer an established aquarium with live rock and a deep sand bed. Be sure to feed them chunks of frozen meaty foods to help avoid exhausting the sand bed of food, leading to starvation of the snails.
