What is this fish

While browsing I came across this article and I'm curious about a fish that was not identified.

It is the one with purple and orange with the pike blenny.

If you're talking about the pic 10, then the species name in the caption, Chaenopsis alepidota, seems refers to both fish (common name: orangethroat pikeblenny).

yes the colored one is male and the muted one is female
