Pistol Shrimp aka Starsky & Yellow Watchman Goby aka Hutch
When we brought Starsky & Hutch home, we were instructed to make sure that we put them into the tank together so they would not loose one another. We did as instructed and wouldn't you know it, Starsky zigged and Hutch zagged. Doodle and I looked at each other and exclaimed "they are above our capabilities"! I stressed all that day and night wondering how they would get along without the other. Of course, it eventually dawned on me, the tank is only 55 gallons and there are only so many places for them to hide. Needless to say they are together.
I wish I had videoed Starsky clearing the sand, he worked like a bulldozer moving the sand around while Hutch stood guard. It was a blast to watch. I found this video on YouTube by Maximus Reef that is a great example of what Starsky does.
Starsky is a type of pistol shrimp which means they snap their claw together to shoot a stream of air/water when they are threatened. Jorge with Pure Reef said you will hear a snapping noise when this happens... guess what, he was right! The tank lights were off, but I could hear a snapping noise. They are just too cool!
