Lawnmower and Barnacle Blenny Compatability

[Zalick]

I have a lawnmower blenny who roams the whole tank. if I add a barnacle blenny, will the lawnmower attack it to death?

Everything I've read said one blenny, but I didn't find much about the second being a barnacle since it hides most of the time in a tiny hole.

If the lawnmower blenny is in the 300g you have in your disclaimer, adding one of a similar size should be fine.
