@bassplayer, i could probably write 5000 words on improving "fish id" ability. Since I am probably not going to be diving the next few days, I will do a detailed write up and post it here. In the meantime I see others have suggested Humann and DeLoach books. The two books pictured below are beautifully illustrated, and invaluable resources. There is much overlap in these two books, if I was going to buy only one it would the one on the left.
Jenny, they are called "Spot" or Spot Croaker, Leistomus xanthurus. In the Drum family of fish. They can be found in the Kells books above. Not sure if they are in the Humann book. Those were over on the east side in shallow water around the rocks in front of the sea wall. I have also seen them on the westside usually on the last bridge piling that touches dry land, in shallow water.
Went to the bridge for diving today and yesterday. The park was never full on either day, however this morning there were three different church groups, church people out numbered divers 4 to 1. By the time I exited the water at about 1300, the park was 98% empty, I guess because of the rain. Visibility on Saturday was the best of the week at 40ft. Visibility today was 30ft. Sea temp yesterday 84f, sea temp today 83f. I saw one moon jellyfish yesterday, none today.
Snorkeled the trail before diving both days, did a REEF fish survey both days, 54 species counted both days. Entered the west side at 1015. Did a REEF fish survey today while diving, it was number 5000 for me, thirty years of doing REEF fish surveys. I have been trying to find species of nudibranch new to me lately. I have been having success, but some of them are so tiny getting a good image is at the limit of the LX10 even with a 10+ diopter. Respectively, Number 5000, Christmas Tree Hydroid Nudibranch, Evelines Learchis, and Planehead Filefish.
