Camera settings

Those are awesome pictures.

Yes parallel to the glass is an absolute must. I have a bowfront tank so it gets tricky at times. My macro lens is much more prone to distortion than my others if I'm not absolutely parallel. Stopping down the lens helps alleviate distortion.

 

Great tips and pictures! Keep 'em coming!

 

some of my Fav pics of my tank where taken before I bought my DSLR. So that being said I'd have to say a DSL is not 100% required to get Great tank shots.
As ReefSparky said "Volume" is key. Even with my 50D I still take 10 shots and only like 1.
If colour is an issue try tuning off your actinics so that the camera only has 1 colour temperature to deal with. This will also make white balance a lot easier.

 

That's a great picture of your sailfin Jason!

 

WOW! All those shots are great. Makes mine look like crud!

 

I totally agree! I was just gawking at it in awe!

 

That was taken with a 6MP Fuji point and shoot 2 years ago. So don't think you can't get good shots without a DSLR

Thanks BTW
