Howdy! I'm a grad student at Texas A&M looking for some fish ID help. I was in Galapagos in May and did some basic dive surveys. Took video with a GoPro and what you will see here is a screenshot of me playing back the video. I apologize for the quality and the fact that it's not zoomed in.
I have no idea what this little guy is, but I am seeing a lot of them in various videos and I believe they are juveniles. Someone else has suggested juvenile Chameleon wrasse (Halichoeres dispilus) but I'm still not sure. PLEASE help!! :)
