At a glance the quick version
Wikipedia gives shell lengths of 25-86 mm; LiveAquaria lists a maximum of 2 in (about 5 cm) for aquarium specimens.
Looks how to spot one
Thick turban-shaped shell
A sturdy, top-shaped shell with about five whorls, knobbly at the shoulder, in olive, green, brown or grey with white streaks or checks. The opening shines with a rainbow sheen inside, and a round, hard 'door' (operculum) seals it.12
Personality what they are like
Peaceful and slow, spending its time grazing. Its size means it can push loose rocks aside as it moves.2
Daily activity how busy a day looks
Constantly grazing over rocks and glass. It needs lots of open surface to feed on and some places to tuck away.2
Grooming and care the hands-on bits
Rated easy. Drip-acclimate it slowly, keep water stable with low nitrate, avoid copper-based medications, and secure rockwork so it cannot topple stones.2
Home where they are happiest
An established marine aquarium with algae to graze. LiveAquaria gives 72-78 °F (about 22-26 °C), pH 8.1-8.4, dKH 8-12 and specific gravity 1.023-1.025. No minimum tank size was given by the sources.2
Food basics what goes in the bowl
A herbivore that scrapes algae from rocks and glass. Offer dried seaweed if natural algae runs low.2
Company who they like around
Peaceful with fish, corals and other invertebrates; usually kept as part of a mixed clean-up crew.2
The story where it all began
Wood described the wavy turban in 1828. Over the years it collected several other names, such as Turbo tessellatus and Turbo fokkesi, that are now treated as the same species. Today it is one of the most common algae-eating snails sold for reef tanks.1
Fun facts for the dinner table
- 1
The inside of its shell opening shimmers with a rainbow-like sheen.2
- 2
Turbo snails close their shell with a hard round 'door'; in related species these are polished and sold as 'cat's eye' jewellery.3
- 3
The Turbo genus goes back to the Upper Cretaceous, about 100 million years ago.3

It is strong enough to bulldoze loose rocks while searching for algae.2
Recognised by the official bits
- Taxonomy (via Wikipedia)
- Described by Wood in 1828 as Turbo fluctuosus (family Turbinidae); the aquarium trade often spells it 'fluctuosa'.1
The care rhythm Furry Diary remembers it for you
A typical home-care rhythm for a Turbo Snail. It is our own starting plan, not a vet's advice, and you can change every line in the app.
- FeedingDepends on species, many feed from the light and the watervaries
- Salinity checkevery week
- Water testevery week
- Top-upTop up evaporation with fresh RO water, not salt waterevery day
- Water changeAbout 10 to 20% of the waterevery 2 weeks
- Light checkevery month
