Re:
[quote:d7b7c9b5="loupgarou"]The tank glass must either be optically pure (ie: totally colorless - eg: acrylic or mineral/sapphire glass) or very thin, otherwise it will offer up a green tint that you may have difficulty correcting digitally.

Chris,
Good summary, but got cut off towards the end. You may have to split the post.
On the point above. It think it should be:
The glass should be as thin as possible to avoid chromatic aberation. If using thick glass, shoot perpenticular to the front pane. Quality/clarity of the glass is critical to getting sharp pictures. As for the type of glass, avoid using tinted glass as that will tint your subject. Ideally, colorless glass or optical glass will be the best option. However, photoshop does offer color correction if you are shooting through tinted glass.
Cheers,
I have dwarf cichlids in my tanks! Do you?
