Two lawnmower blennies in a 140g?

Accidentally ordered two of the buggers. They are about the same size, just placed into QT. I know they can be aggressive towards each other but my tank is naturally setup into two territories. Will this definitely be a problem?

It may or may not be a problem. What helps is they are being added simultaneously and tank size. However, they can be pretty aggressive to each other and the aggression may not fully show itself until further down the road.

I will probably proactively rehome one. I don't particularly want two anyway. I also have a yellow watchman/pistol pair and I'm worrying with 2 blennies some aggression may spill his way.
