Maintain these water conditions for optimal health and vibrant colors
Astraea snails graze film algae, diatoms and fine hair algae from rockwork and glass. They suit stable saltwater aquariums with mature surfaces to browse and should be acclimated slowly like other marine invertebrates.
Place the snail carefully onto rock or glass after acclimation. Astraea snails can struggle to right themselves if they fall upside down, so check them after introduction and gently turn them upright if needed.
This is a living marine invertebrate. We dispatch suitable livestock with a licensed live-animal courier when conditions are safe, and the Live Arrival Guarantee applies when the arrival guidance is followed.
