I have a watchman Goby, a Diamond Goby, and a Clown Goby. They have great color and are a lot of fun. The Clown will sit on rocks, power heads, or just hang on the glass and follow you around the room. He loves to see what is going on outside the tank. The Diamond is a sand sifter and over one weekend, he managed to cover one 15 pound chunk of LR
. THe next few days he uncovered it and moved all the sand to the other side of the tank. The watchman, he just hangs out behind the rocks (and under them) and is always peeking around the coners to see what is going on. He does not scare away if you are looking at him or near the tank, but he just sticks his head out and stares at you.
All in all, they are fun to watch and I have spaced out many hours just watching them watch me.
