he really pisses off my watchman goby... and scares away my other fish.. being that its HUGE. he looked smaller in the tank before i bought him . I think it may be a red lip blenny though....

This is a redlip, you have to pull up the pic from the side. The one above the royal gramma.

It could be stress spots on him in your pic though, does he change color?
Does he have his own cave? Maybe he is just trying to find a spot to call his own in your tank. What size tank?
