Check out the website, we went Snailing yesterday on the most beautiful flat covered with many different kinds of Macro Algae’s, beautiful Sponges and live everywhere you look. I will be adding these to the site and many other inverts and Clean Up Crew over the next week. Snails play such an integral role in the reef tank and these beauties are covered with coralline algae and hungry for all of your nuisance Algae. Order this week and we ship out on Wednesday everything is overnight and I just added $30 shipping to everywhere in Florida. I will be adding a lot more to the site over the next week, if you haven’t been on, check it out. Lots of beautiful WYSIWYG Corals, special releases from the outdoor coral farm and many articles to help you with your reef tank journey!
