Spotting

Since you have different fish in each photo, you need to make multiple spottings, one for each species. And I can identify most of the species here for you. In the first picture you've got a butterfly fish in the family Chaetodontidae. The second picture has to many different species in it. The third has a pair of Tomato Clownfish (Amphiprion frenatus). And the last one has a yellow tang (Zebrasoma flavescens). Hope this helps.
