After reading this, I checked at around midnight, and the dragonfish was swimming around very actively. While he was doing so, I filled up the holes into his cave with gravel. I did this because I was worried he would die in there, and it would be pretty much impossible to get him out. For a while, he hid in another spot. Now, he has found another hole into the cave.Yes they are very nocturnal.
The goby needs a place to retreat to and hide. I would uncover his caves because they help him feel secure. If you don't see him for a time frame you might try putting a treat in the water (tubifex worms, blood worms). Or check on him in the wee hours of the nite. Here's a couple of links that might help.The person who gave me the dragonfish also gave me a black molly, a platy, five tetras, and a suckermouth. They were all from the same aquarium (FW). Also, I've heard that dragonfish get up to just over a foot in captivity.
