Should i replace the clowns for frag tank

[Jake_the_reefer]

So I have decided to convert my 14g biocube into a nano frag tank. I currently have 2 small cinnamon clownfish and a bicolor blenny in the tank. I plan on keeping the blenny for algae but I'm not sure if I should keep the clowns in the tank. Would they be fine with living in a frag type system? I have hiding spots for the blenny but turning in preparation for frag racks I got rid of most of the live rock which has lowered hiding spots for the clowns.
Should I ditch the clowns for a wrasse or keep them. I care less about functionality in a frag system and more about the general happiness of the fish.
