Recently I picked up a Dracula goby. I dug them a burrow and him and the pistol took right to it. They either dug a new one in the back or extending the small burrow I made to the back. He’s always in the back of my tank which is kind of disappointing because it’s hard to see him. But my issue is is that where he’s hanging out in the back is inches from my fire fishes little home. My fire fish used to always come out during feeding time and periodically through the day. Since I added the Dracula the fire fish never comes out and today I saw him peak his head out while the Dracula was eating and then ducked right back in. Any advice on what’s going on or how I can fix it?
