I have a banded(dragon) goby, a red fire fish and a green barred dartfish like here : Saltwater Aquarium Fish for Marine Aquariums: Zebra Barred Dartfish
I was checking my tank just now with the red led light and they are all under the same rock, in the same little cave, side by side. I figured they would have started chasing each other and fighting over the little cave. I had the big banded goby first then added the dartfish several months later and I just got the fire fish off of someone breaking down a tank a few days ago. It's not like they were all introduced at the same time and just ended up in the same cave. I thought for sure the dart fish and fire fish would have went after each other. The fire fish started at the opposite end of my 75 and ended up there.
