Lawnmower Blenny and getting another blenny

[Ryan5]

I have lawnmore blenny right now in my 50 gallon tank and I was thinking about getting another blenny either a canary or midas blenny. I was wondering if there would be any problems with them if I did decide to get one of them.

I have a lawnmower with a Midas in a 125 gal. I have no issues between them.
