Continuation of Challenge Blue

A friend of mine often comes with me if I'm doing a photo challenge over a lunch hour. I definitely enjoy the company and the help finding appropriate subjects! She spotted this gem.

Taking this picture actually had an added dimension of difficulty - the fish tank is part of a wall that divides the children's library from the entrace to the main library. I felt the need to try very hard to ensure there were no children in the shot, behind the glass, in addition to hopefully getting the fish in focus - and I succeeded! He almost looks like he's staring out at the camera. I've seen plenty of blue-tinted fish before, but this guy really stands out. I may go over there before the library opens one day (so no risk of appearing creepy!) and see what other shots I can get of the fish - maybe using colour accent to really make a fish or a plant stand out.
