I like the logos you have come up with. The coloring is good, and I like how Coral and Reef are in two different colors. For entries #1 and #2 I don't like the black, it's a little too bold. The teal on #3 and #4 looks great. I really like the font of #3. Not sure how I feel about the grey and white background behind the fish in #3 and #4
#42 is still my go to. Would like to see a couple changes though. Can you do a different fish? Maybe something more tropical? For the text, can we pull the purple color from the image to be used for "Reef"? Also, make the text a bit larger? It looks small next to the image now that we have taken off the slogan.
