Decent visibility. Lots of beautiful strawberry anemones. Variety of nudis like dendros, dironas, dorids, some really cool ones that shape resembled lemons but were all white with like a highlighter yellow outline. Not sure what those were. Also saw a baby king crab

Interesting, I did not know there were strawberry anemones there!


Perhaps a yellow margin dorid?
