Cittarium pica – Nocturnal Reef-Grazing Snail

Cittarium pica is a marine snail native to the Indo-Pacific region, recognizable by its spiral beige shell marbled with black. Primarily active at dusk and dawn, it plays an essential role in the natural maintenance of the reef aquarium.

An excellent algae grazer

This gastropod is a very efficient algae grazer, particularly suited for well-established aquariums with rocky surfaces, glass, or substrates colonized by algae. It contributes to the natural regulation of the algal film without disrupting the tank’s balance or bothering other inhabitants.

Nocturnal and discreet activity

Unlike other snails active during the day, the Cittarium pica moves and feeds mostly at night, making it an ideal addition to a varied cleaning crew. It naturally frequents rocky intertidal zones and coral reefs rich in microalgae.
