ccg you'll get better pics (no flash reflection) if you hold the camera above where you're trying to take the picture and aim down on the focus point
see no flash reflection: http/img.photobucket.com/albums/v607/MXPX4318/IMG_0993.jpg
also try and find a "flourecent lighting" setting on your camera and maybe try some shots with the room lights off and just the tank lights and no flash for shots like this: http/img.photobucket.com/albums/v607/MXPX4318/1e217caf.jpg
As for the Pleco, I'd disagree with both options suggested above.... From the pic it looks like it's only got 9 spines in it's dorsal fin, ruling out a Sailfin (13 spines) and if it hasn't grown much in 12 months, it kinda rules out a Common......
As for what it actually is... haven't got a clue !!!
