I got the tang last week and the goby today...the goby is the biggest one I have ever seen at well over 10 inches. I thought he was a weird eel at first.
Looks great! Yur gonna love/hate the goby. Highly intersting to watch but can be a bit frustrating on the tank design.. LOL
I gave up on any hope of the substrate in my 27 gal looking anywhere "smooth" some time ago. I have two of them and they definately live up to their name... 8O
