yeah SITC drills tanks and I don't believe its all that expensive, I would do at least a 55g the more I thought about it at work the more I thought a 75g tank would work better for you. According to my "The Complete IDIOT'S guid to: Saltwater Aquariums", best book I EVER got, and 45g tank is 36x13x24, 55g 48x13x20, 58 36x18x21, 75 48x18x21, 89 36x24x24. I never knew they made a 89g tank and keep in mind these are just standard sizes and there are different shapes and builders who make things a bit different, afterall my 125g tank is only 5 foot.
