You are welcome...I am glad you found something you liked that worked out. The way I see it, this hobby can become quite complicated on its own without us inadvertantly adding to the issues. I commend you for doing the research on the fish first, too many don't. I too, have admired the catalina goby and thought to do a cool water specie tank. I hadnt because of the warm weather and ambient temp in the summer, but I have recently gotten a chiller that would be suitable for a small tank and am seriously pondering this for my next tank.
Good job on your choice, clown gobies are quite cute.
