This is an Aussie reef, CADE 900, so about 98 gallons with sump. I call these "periwinkles" but happy to be corrected. They... do well. Constantly breeding. There are always multiple sizes, from the hoary oldtimers completely covered in coralline algae or even xenia, down to tiny little fellers who I guess are only weeks old. I constantly see eggs on the glass. The worst part is, even with this many, the glass still fogs with algae. Why can't they clean it?!
