Yo ho not so little fishy

Had to clean Nero's tank today - a mammoth 2 hr job which I don't enjoy very much. But here he is in his tank so clean he can see himself reflected which confuses him no end.
I've done this shot before but still strive to get it to look flawlessly like there are 2 fish there. This one is a wee bit better than the last.

Thank goodness there aren't 2 fish there though. Nero is now 10 inches long and has outgrown his third tank in as many years. Not sure the floor boards can take the weight of a bigger tank so he may have to go live in a pond somewhere if he gets much bigger!
