Can anyone ID these fish for me?

I figured the right is a regular algae blenny but the left is different. Anyone familiar with them?

When I google that they don't look similar at all.. I caught these guys (6 of em) all together at a reef in the atlantic. If that helps

Panamic barnacle blennies is what your google search is probably bringing up...
There are a few different types though.
Do they hide in those barnacles?

The blenny on the left looks like a Pearl Blenny (Entomacrodus nigricans). Apparently, they feed on algae.
