At a glance the quick version
Maximum about 1.5 inches; the genus ranges from small to medium-sized snails.
Looks how to spot one
Spiral shell
A small to medium sea snail with a tall, pointed, tightly spiralled shell. Species differ in shell colour and markings, from bluish to yellowish and patterned forms.2
Personality what they are like
A calm, unhurried grazer that does most of its foraging at night, working over rock and sand for algae and leftovers.1
Daily activity how busy a day looks
Most active at night; burrows into the sand and climbs over rocks while feeding.1
Grooming and care the hands-on bits
Use slow drip acclimation, keep water parameters steady with low nitrate, and never use copper-based treatments in its tank.1
Home where they are happiest
An established reef or marine tank with a deep sand bed and live rock. Stable, fully marine water at about 22-26 C, pH 8.1-8.4, salinity (specific gravity) 1.023-1.025 and dKH 8-12.1
Food basics what goes in the bowl
An omnivore that eats algae, detritus, leftover food and fish waste; a mature tank supplies most of its food.1
Company who they like around
Peaceful and reef compatible; works well in groups as part of a clean-up crew.1
The story where it all began
Bruguiere named the genus Cerithium in 1789, and its fossil record stretches back to the Triassic period. Today these snails are among the most common members of marine clean-up crews.21

Owner questions the things everyone asks
How often should I feed my Cerith Snail?
In a mature tank, your Cerith Snail will find plenty of algae and leftovers, so you may not need to feed it directly. Furry Diary's starting plan suggests that feeding depends on the species, and many snails feed from the light and water. If you do supplement, offer a small amount of algae or sinking food once or twice a week, and watch that it gets eaten.1 Furry Diary plan
What does a Cerith Snail eat, and what should it never eat?
Your Cerith Snail is an omnivore that happily eats algae, detritus, leftover fish food, and fish waste. It should never be exposed to copper-based treatments, as these are toxic to snails. Always keep the tank free of copper and avoid any medications or additives containing it.1
How much space does a Cerith Snail need?
Space requirements vary depending on the species and the number of snails you keep. For a single snail, a small reef tank with live rock and a deep sand bed is usually enough, but for a group, a larger tank is better. Ask a good breeder or an exotic-pet vet for specific advice for your species.
What temperature, light or water does a Cerith Snail need?
Your Cerith Snail needs stable marine water at 22-26°C, pH 8.1-8.4, salinity 1.023-1.025, and dKH 8-12. It thrives in an established reef tank with live rock and a deep sand bed. Furry Diary's plan includes weekly water tests and monthly light checks to keep conditions steady.1 Furry Diary plan
How often should I clean a Cerith Snail's home?
Regular water changes of 10-20% every two weeks, along with daily top-ups of fresh RO water, help keep the tank clean. Weekly salinity and water tests ensure stable conditions. For a detailed cleaning schedule, ask your vet or a good breeder. Furry Diary plan
Can a Cerith Snail live with others?
Yes, your Cerith Snail is peaceful and reef compatible, making it a wonderful addition to a clean-up crew. It works well in groups and gets along with other calm tank mates. Just avoid aggressive fish or invertebrates that might harm it.1
How long does a Cerith Snail live?
Lifespan varies by species and care, but many Cerith Snails live for several years in a well-maintained tank. For a more precise estimate, ask a good breeder or an exotic-pet vet who knows your specific species.
Can I handle a Cerith Snail?
It is best to avoid handling your Cerith Snail, as they are delicate and can be stressed by being out of water. If you must move it, use a soft net or gently guide it onto a rock. Always ask a vet for safe handling tips.
