Just dived in

[Scythanith]

This has a little white balance correction, some black point adjustment, some more definition, and some output sharpening. By nooooo means perfect (I mean my editing, no your pictures haahaa), but shows off the patterning a little better

As for the camera info, listen to Steve, he's a pro

A couple extra pointers:

Shoot straight through the glass, NO angles!
Wear dark clothing, less reflections off the glass.
Use a tripod.
Use manual focus for stationary objects. This, combined with AP, can really showcase what you want to be the focal point of the photo.
If you can set WB easily enough (you can), set it to ~10,000K and start there. That's essentially the same as "cloudy" setting.
It has been mentioned but shut off the power heads and return pump.

Take lots of pictures and mess around with your settings! Once you find what you like you can probably save the entire batch of settings under a custom label and return to them every time you're shooting the tank.

As for the wife shot, Steve hit it on the head, bounce that light! Also, the camera doesn't always know what's right, you may have to dial in a bit of flash compensation. Usually looks like a little lighting bolt and a +/-. Your picture may have required a little "-".

Cheers,
Scott
