That is my Dragon Goby, out and about to some extent. His name is Fred 2. Fred 1 was possibly murdered by a tank mate at school, or possibly messed with by kids in other classes who had been caught at me and my friends fish tank before with a fish net. 
RIP Fred 2 will sometimes move around during the day, but he usually chills out to the side of the sjull, against the window, or in the back against the window, or in the stump. But at night he likes to party and will be swimming all over the place and exploring every nook and cranny in the tank and get his munch on, he likes little Tetra food granules, sometimes he’ll have a brine shrimp pellet. He and my Bichir share the tank with one little catfish, seen in the videos, but he is camera shy, haha. UPDATE: I am currently updating from gravel to sand today. 4/19/09. UPDATE: The gravel is gone and the sand is in. I’ve added an air pump into the mix. The sand is doin’ pretty good and they love it!
