Description
Tectus niloticus, commonly known as the Egyptian pyramid snail or marbled cone snail, is a large marine gastropod prized by advanced aquarists for algae control and substrate bioturbation. These robust snails actively graze on nuisance algae, diatoms, and biofilm across rocks and glass, reducing maintenance demands in established systems. Their substantial size and feeding behavior naturally aerate substrate layers, promoting beneficial microbial activity and preventing anaerobic pockets. Tectus niloticus thrives in mature saltwater and brackish aquariums with stable parameters and ample grazing surfaces. Hardy and long-lived, they represent a sustainable biological solution for algae management while contributing ecological balance to reef and community marine setups. Suitable for tanks 75 gallons and larger with adequate food sources and calcium supplementation.
