Dragon Gobies, are pretty neat fish. With time, they should become more active, but keep in mind that they are not very active fish. They should also be kept in a slightly brackish aquarium.
I love my dragon goby. I've had him for a year, and he's over a foot long now. He's very active, always swimming along the bottom, digging tunnels and filling old tunnels in. He loves shrimp pellets. Great fish!
no lol. As far as activity goes, they can be very boring. On the other hand, in the right set-up they are very active burrowers. In the wrong set-up your lucky to see any action. Mine loved to dig in fine gravel under large stones. Keep in mind that this will undermine the stability of any decor you might have. Further than that and filter feeding, there isnt much to dragon gobies
