Dr. Mac's Comments:
Astrea snails are excellent general algae grazers that help clean many types of algae from rockwork and tank walls. They are hardy, easy to keep, and do not bother any other reef tank inhabitants. We recommend keeping 1-2 Astrea for every 3 to 5 gallons of tank size. These are great snails for algae control but should be mixed with a variety of other snails for best results.
