Well, after reading all of the very appreciated comments I decided to go and buy one. I got a smaller one, maybe 2''. I put him in the tank and he hid for awhile. Later that night I was skimming through my tank with a flash light and caught a climpse of him swimming about half way up my tank. I immedietly turned to watch him and as I did, he got spooked or was trying to escape and just about did.
I caught him in time and today I went out and got a nice cover so he is all good and tidy.
Ive gotta say, he is one of the coolest fish I have ever purchased. He will sift through the sand and find pieces of rubble rock, sift the sand out, and then take the rock back to his "den". Deffinetly is a people fish. Always watches me as Im watching him.
I would really recommend him for anyone that wants a fun fish with personality but make sure your tank is 150% locked up. I would hate to wake up and see Goby Jerky.
