blennies and fire fish and stocking

[reef tank 2.0]

I have a Molly miller blenny, and am considering adding a couple firefish to the tank.
I know that firefish dart into the rocks and take cover at night. But blennies live in and on the rocks as well.

what chance do I have that the blennie won't bother the firefish?
I have a 32 x 24 (80g cube)

I will have 2 clowns, 2 cardinals (banggai or pj), dottyback, and MAYBE 2-3 chromis
I'd like some swimmers, but the ones I like, need a bigger tank.

I'm still keeping my eyes open for some fish at the LFS that pop up that might be a good possibility. but I don't know how many more fish I can get without being overstocked

Firefish should be fine with the blenny. Its when you get to multiple gobies and blennies of the same kind that there are issues. Blennies really dont like other blennies
