just noticed a problem opening the 2 first images in my previous post. Here another try.
Looks like either Boga or Bonnetmouth. Both species are share close resemblence, but can be seperated by the distance between the dorsal fins: In Boga the 1st and 2nd dorsal fins are connected and in Bonnetmouth the two fins are seperated.
They do look similar- bogas are more likely to have the clearly multiple stripes and are much more common.
Interestingly, genetic analyses have shown that bogas are just a very sleek grunt- they fall right in the middle of Haemulon, the grunt genus, and have recently been moved into the grunts.
