Care
The Mexican turbo is a large, solid turban snail from the eastern Pacific, with a shell 2.5–8.6 cm long (most sold at 2.5–5 cm). The shell is olive, green, brown or grey with white streaks or a chequered pattern, has knobbed shoulders and coarse spiral ridges, and an iridescent interior. The round operculum has a raised white, granular centre and green beaded ridges. Clean-up crew: it is one of the most effective algae-grazing snails for reef tanks, eating hair algae, film algae on glass and rock, and diatoms. A common rule of thumb is about one snail per 20–40 litres, depending on how much algae there is (general guidance, not from a source). Because it eats so much, it can starve once the algae is gone; offer dried seaweed (nori) if the rock looks clean. Large snails can knock over loose frags, so glue frags down. Set-up and water: stable reef conditions with good calcium and alkalinity for shell growth. Acclimatise slowly with a drip, as snails react badly to fast salinity changes. Like other turbos it can struggle to right itself if it falls on its back on sand; turn it over if you see it. Temperature: it comes from fairly cool subtropical water, so it prefers the lower to middle part of normal reef temperatures. Our sources have little on this species' care; the care figures are general guidance, not from a source. Copper: copper-based medicines and some plant fertilisers are toxic to shrimp, snails and most invertebrates. Never dose copper in a tank holding this animal, and check fertiliser and medicine labels before use. Sources: Wikipedia (en.wikipedia.org/wiki/Turbofluctuosus). Checked October 2026.
Diet
Herbivore. Grazes hair algae, diatoms and film algae from rock and glass. Supplement with dried seaweed (nori) or algae wafers once the algae runs low. It does not usually eat coralline algae in large amounts or touch corals.
Breeding
Sexes are separate. It is a broadcast spawner that releases eggs and sperm into the water, which can briefly cloud a tank. The larvae are planktonic and rarely survive in aquariums, so it does not breed in home tanks in useful numbers.
Compatibility and tank mates
Peaceful and reef safe. Hermit crabs may kill it for its shell, and wrasses, triggers, puffers and some crabs prey on snails. Can bulldoze loose frags. Fine with fish, shrimp and corals.
