I love blennies myself, but they do often seem to go after certain corals so you’d have to look into your corals and a particular species of blenny are likely to cohabit well.
If you decide to go with blue spotted jawfish it’s worth making sure you can keep your tank cool enough for them.
From the article I linked below:
“
Cool-Water Fish
As if the call for grand-size systems with few if any roommates and great bunches of sand weren’t enough, these fish are not really tropical animals. That’s right; they live in cooler water. The Eastern Pacific coast, where the jawfish is found, is cooled by the California Current, a stream of cold water from Alaska. This makes it surprisingly cooler than you might think.
The practical implication is that water off the Californias is appreciably cooler than the same latitudes in the West Pacific, with the habitat of this jawfish being mostly in the upper 50s to upper 60s, and rarely lower 70s.”
Given plenty of hiding spaces, the beautiful blue-spotted jawfish will thrive in your large saltwater aquarium!

I looked into these jawfish at one point but while there are lots of people who say they do “okay” for a few months at normal reef tank temperatures it seems that they often die much sooner than they would if they were kept at a proper cooler temperature.
