Zoanthids

These Zoanthids are the larger variety, with each polyp head being about the size of a dime. Opening up quickly, they quickly became my favorite zoanthid in my 29g reef, and looked great under PC lighting. Unfortunately, they began to shrivel up and I almost lost this colony. Apparently, these zoas demand lower salinity and when my tank accidentally reached the specific gravity of 1.028, they let me know. Keeping my tank at 1.025sg helped them fully recover.
