Hello, I have this stony coral I have been trying to save, however I'm not sure what it is. These pictures are under white light. I mostly care for its id now because I want to peroxide dip it to remove the algae however I don't know the correct ratios. If anyone has any suggestions I'm open to other ways of removing the algae. It's a little difficult to manually pull. We have about 20-30 blue leg crabs, 1 black urchin, 1 tuxedo urchin, and 1 snail (45 gal tank). I was hoping the cuc would clean it but it hasn't been touched.
