Uhm...huh?
I've got a 65 with that footprint, its nice. Out of what you listed I'd say the 40b. Depending on what fish you want to keep though I'd drop the extra 25$ and get the 65 if its on sale as well.
Yes your depth visibility doubts are unfounded...I can't even figure out by what logic you came to that
Are you just worried about having more stuff for them to hide from? Is there a viewing angle issue going on? Do you think the light won't reach the bottom of the tank so it'll be dark near the bottom (not the case at all)?
