Starry Blenny and lawnmower Blenny

I really want to add these two fish but I don’t want them to fight. Would a 100 gallon with tons of rock allow enough space for each of them or should I just get 1?
Is I can only get one, which should I get?

Get me only one because they will find ght to the death. Starry gets my vote!
