new direction, need suggestions

So i was all set on getting some corals in my tank and keeping my fish stocking at a min. but ive changed my mind, my tank is stable and nitrates are at 10ppm. taking care of the tank right now is a breeze, so i decided to read more about coral and wait to set up my 75 gallon when i leave my upper apartment.
so since no corals im in the market for a new fish!just as fun. id like somehting very small,and will co exist well with my other inhabitants. something that utilizes the caves and crevices of live rock,ears are open.
tank specs are below

 

How about a Sixline Wrasse. I have a pair that love to chase each other around through the rocks.....But what they really love is to catch each other. Unfortunately my attempts at collecting the eggs hasn't worked out so far.

 

Banded Jaw Fish

I recently stumbled across a very friendly (despite his appearance) Banded Jaw Fish. He is black & white--I have a few pics but since he loves to duck into the coral/rock so much he is hard to capture in his "true" nature. does require frozen food though. I would also try to find one small for your sized tank. I have been in the salt fish game twelve years now, have shifted back and forth between all coral and all fish tanks. I just this past year went back to fish and wish I had discovered this guy sooner.

 

A pygmy angel would be a nice addition. They love to swim in and out of rock continually prowling for alage...8)

 

A blenny would be the shiznit...........

 

thanks for quick replys. i thougt about the sixline but he well be in comp. with the scooter blenny for pods, or what ever is left of them. i also thought about a flame angel but i think hes a lil to large for my setup. The jawfish is something i would consider if i can find one around here. also i thought about a neon goby, he also is a cleaner. does any one think my scooter blenny would be alright with another fish in the blenny or goby family? anyone know whats the adult size of the yellow watch man goby, and midas blenny? what kind of bioload do they carry. thier sizes vary from site to site.
