Great having you with us. You will like it here, and I am sure you will have a lot to contribute.
The fish you feature in the picture you included, the Gobiodon Unicolor, is not one I am familiar with. Would you tell a little more about it... like its habits in your tank. I would like to know more about it.
Also, you mention having a SW
tank years ago. If you do not mind spending the time writing, I, for one, would love to know how you see the hobby changing compared to 'the olden days'. =]
