They are great fish, although I'm not sure how one can tell the difference between the hybrid gobies and the sharknose gobies. I stared at the two pics on ORA's website and really can't tell what they're talking about lol; they look the same to me. In any case, that's a great-looking pair you have. They're cool to watch.
I have one similar (a sharknose or a hybrid) that lost its mate awhile back. He's a fav fish in our house
