I think part of it is the way that you did your scaping which helps to make it look larger along with the the fact that the tank has more length to it and not as high, if that makes sense.
Makes sense to me...LOL
Thanks everyone. I have the itch to upgrade to a 15 gallon. Just to give me a little more room for husbandry, and glass, cause this cheap acrylic scratches too easy. And now it doesnt look as nice looking through it.
