Astraea snail is an excellent algae grazer for the marine
aquarium. It's not a fast moving snail but it does a good job of
consuming diatoms and other film algae from the sides of tanks as
well as live rock. This species is not known to climb out of the
aquarium. We collect various sizes, but most are 1/2" to
1". Sold in lots of 10.
