Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Western Atlantic Ocean: Gulf of Mexico, Florida, Caribbean.
Size: 2 inches (5 cm)
Natural Environment: Inhabits shallow intertidal areas where algae and diatom covered rock and ruble accumulate.
General Husbandry: Common in the home aquarium trade.
An extremely good scavenger of unwanted green microalgae, turf algae (hair algae) and brown diatom algae, and because of their small size, is less apt to disturb or knock small frags over.
Another good point is that they are long lasting, with many lasting years in the aquarium. They also do not harm any creatures they travel over, making them one of the more desired snail species in hobbyist aquariums.
Sensitive to salinity changes as they are very shallow intertidal water creatures, so initially acclimate as noted below. Recommend having at least one per five gallons and if their diet appears to be insufficient, provide them some vegetable-based tablet foods or dried seaweed/Nori.
FYI: Even though widely sold in the trade as an 'Astraea' species, the genius name has been changed to that of 'Lithopoma.'
Keep in mind these snails have a difficulty righting themselves if they fall and are not right side up. Therefore, always place newly acquired snails or those that fall off objects in the aquarium when seen properly with their foot contacting the substrate.
Experience Level: Beginner
Aquarium Environment: Reef or fish-only aquarium
Coral Safe: Yes
Fish Safe: Yes
Invertebrate Safe: Yes
Acclimation Time: Sensitive to specific gravity/salinity changes, therefore be sure to adjust the bag's water to that of the aquarium in which it will be placed by slowly adding small amounts of aquarium water to the bag every few minutes. In most cases, this process should take at least 15 minutes.
