Starry blennies get quite big, and the midas gets pretty large also. Starry blennies get to be about 5" long or more. Midas about 4" or so. I think that the midas blennies are less aggressive. Starry blennies can get mean, and they also are omnivores (although most reefers think that they only eat algae). That is important to know, in your case, because they can and will eat small fish or shrimp.
