Money Cowrie Snail
The Money Cowrie Snail (Cypraea moneta), also known as the Ring Cowrie, will grow to roughly 1" in size and is an excellent algae eater for a reef aquarium. No more than 1-2 per 10 gallons should be used as these mollusks can starve fairly quickly. They cannot right themselves if they fall onto their back or side. Money Cowries are also very sensitive to salinity changes, copper based medications, and excessive nitrates. Please acclimate them slowly. They are known to eat film algae, diatoms, hair algae and some species of cyanobacteria. Supplement their diet with dried seaweed sheets.
