Spiny Astrea Snail Astraea Phoebia

The Spiny Astrea Snail is a hardy and efficient algae grazer, easily recognized by its distinctive conical, ridged shell lined with small spines. A valuable member of any reef cleanup crew, it helps keep live rock and glass surfaces free of nuisance algae while adding texture and visual interest to the aquarium.

Native to the Caribbean and Western Atlantic, Astraea phoebia inhabits rocky reef areas and coral rubble zones, where it grazes constantly on microalgae and biofilm.

Primarily herbivorous, feeding on film algae, diatoms, and green microalgae. Supplement its diet with dried seaweed or algae wafers if natural algae is scarce.

Completely reef-safe and peaceful. Excellent companion for other snails, shrimp, and reef-safe fish. Avoid predatory species such as certain wrasses, triggers, and puffers.

Peaceful. Plays a beneficial role in maintaining a clean, balanced aquarium environment.

Ideal for beginners and advanced reef keepers alike. Hardy and easy to care for, though it may need assistance if flipped onto its back.
