just got pistol and yellow watchmen goby

Yeah I'm positive. I have actually caught him "clicking" and chasing fish and shrimp all over the tank. I think i have an unusually brave/aggressive guy though. He is out all the time, and even attacks anything i put in the tank such as my siphon, feeder tubes, etc... In fact, i now have to use wooden tongs to rearrange anything on the sand bed because he will attack my hand!!!! LOL, his nickname quickly became "that bastard"!! ;D
