I like that the plastic is clear except for the handles, they are gray and don't show through. It's for a reason, so you always had to either use a light strip that was just right for her, or you'd end up with a weird shadow in the middle of the tank. They use transparent plastic (actually opaque) which lets in most of the light and seems to scatter it a bit. Don't know, here is a list of aquarium sizes, there are many different aquariums with completely different sizes that have the same number of internal gallons. -Sizes-of-glass-aquariums.html DIMENSIONS (LxWxH)2 1/2 gal 12 x 6 x 85 gal 16 x 8 x 1010 gal 20 x 10 x 1215 gal 24 x 12 x 1215 high 20 x 10 x 1820 high 24 x 12 x 1620 long 30 x 12 x 1229 gal 30 x 12 x 1830 gal 36 x 12 x 1630 grower 36 x 18 x 1233 long 48 x 13 x 1237 gal 30 x 12 x 2238 gal 36 x 12 x 2040 grower x 36 1640 long 48 x 13 x 1645 gal 36 x 12 x 2450 gal 36 x 18 x 1855 gal 48 x 13 x 2065 gal 36 x 18 x 2475 gal 48 x 18 x 2090 gal 48 x 18 x 24 x2 allon 72 x 18 x 22150 gal 72 x 18 x 29180 gal 72 x 24 x 24210 gal 72 x 24 x 2920 X High 20 x 10 x 2430 X High 24 x 12 x 2430 X High 24 x 12 x 24110 X High 48 x 18 x 29
