Conehead Aglae eater Astraea tecta

Astraea tecta, the Conehead Aglae eater, is a dependable herbivorous snail for reef and planted aquariums. This species excels at consuming nuisance algae, including film and diatoms, while grazing naturally on rockwork and substrate. Hardy and low-maintenance, it thrives in stable saltwater or brackish conditions. Optimal parameters: pH 8.1–8.3, temperature 72–78°F, and moderate water flow. Requires adequate calcium for shell integrity. A proven biocontrol solution for aquarists prioritizing natural algae management over chemical treatments.
