Algae and detritus grazer. Reef-safe.

Quick facts

• Size: 1–3 cm shell length

• Temperament: Peaceful

• Reef-safe: Yes

• Role: Film algae, diatom, and detritus control

• Care level: Easy

Aquarium requirements

• Tank: ≥ 30 l; mature rockwork recommended.

• Substrate: Fine sand ideal; burrows and stirs top layer.

• Water: pH 8.1–8.4, salinity 1.025–1.026, temp 24–26 °C; NH3/NO2 0, NO3 <20 ppm.

• Flow: Low–moderate.

Diet

• Primary: Film algae, diatoms, biofilm, leftover fish food.

• Supplement: Algae wafers or tiny pellet crumbs if the tank is very clean.

Behavior and compatibility

• Nocturnal to crepuscular; climbs glass and rock, buries in sand by day.

• Safe with corals and most fish.

• Avoid housing with snail-eaters (certain wrasses, triggers, puffers).

Acclimation and care

• Drip acclimate 30–45 min; match salinity closely.

• Do not expose to air during transfer if possible.

• Keep shells upright if flipped; prolonged inversion can be fatal.

Stocking guide

• 30–60 l: 2–4 snails

• 120 l: 6–10 snails

• 250 l+: 12–20 snails

Notes

• Not a solution for hair algae by itself; pair with other grazers.

• Breeds in captivity; planktonic larvae rarely survive in displays.
