How big can I go while keeping the same light?

My lawnmower blenny is out and about all the time. Maybe when you re-aquascape you will have better luck. I leave a big area of open sand in the front middle of my tank for my fish to congregate in, just a couple small rocks for the gobies to purch on. My orange spotted watchman gobie took about 6 months before he decided he didn't need to hide anymore, so give it time.
