Here is a photo from a month or so ago ... shows the green pattern he displays very little of most of the time (besides when sleeping or a bit anxious).
well, I have the tank lights on, and the flash on, but other than that, usually no other light sources in the room, maybe the computer monitor, but it doesn't face the tank directly.
I have been trying different angles as well as varying distances.
Starting to wonder if lack of a background and decor in the tank might enhance my problems
I do use a few years old Kodak EasyShare Z600 or something to that effect, 4 MegaPixel.
I just need to be a better window washer

Getting a tripod would probably help a little as well
Now worries, they are good enough for me, just not up to the quality I wish they could be.
