Tienes toda la razón Philip el B. splendens no tiene esa dorsal tan larga, tal vez como un ejemplar de la familia Holocentridae. En la fotografía parece que el preopérculo tiene una espina????
Difficult to see on the photographs, but the second is certainly not Beryx splendens (which has a much shorter dorsal fin), but Heteropriacanthus cruentatus (family PRIACANTHIDAE).
The first photograph shows a young carangid, maybe Seriola dumerilii.
About first photo I should say that it's absolutely a Carangid fish but about its genus and species's name, I think it 's a member of Caranx genus like Caranx crysos or Caranx hippos.

En efecto, la observación del Dr. Fricke es la correcta se trata de un Priacanthidae. En cuanto a la especie, encontrada tan al norte del Atlántico,parece indicar que se trata de una primera cita.
I have colected pre and post setleled reef fishes (from 10mm to 10cm mor less) at northeast coast brazil and in the samples i record the first fish in picture Carangoides batholomaei an to the second fish in the picture it seems a Priacanthidae Priacanthus arenatus
