What is the difference between the banded watchman goby and the yellow watchman goby??
Is one better then the other for a reef tank and inverts?:help:

I have a yellow watchman goby and I must say he is by FAR my most interesting fish. He is Mr. personality plus. He always comes out of his cave when I am looking at the tank. He always has the look like " I am such a big fish" and then he opens his mouth at me and puts his back fin up. I wouldn't trade him for the world. I have not had any experience with the banded gobys.
