I like those Yellow Headed gobies. After my Orange Spotted goby died, I was looking for a replacement and saw a Yellowhead at the LFS. I love the way it hovered and cleaned the sand, but it cleaned ALOT lol, and made a pretty big duststorm in there. I decided not get him because my sand is even finer than what they use at the LFS, and I didnt want my water to be all cloudy. Instead, I got a Goby the LFS calls a "Decorative Goby". My friend has had one for like year and has always been healthy, so I figured I'd get the same and try it out. It looks like a Diamond Goby, but it has dark almost rectangular spots on it too. Anyone ever heard of a "Decorative" Goby? I cant seem to find anything with that name on the net.
