They do look pretty neat, one thing to think about is the length of the tank. The reason 100 gal
or 125 gal
are being recommended is the length, or so I assume. No one has recommended a 110 ( bigger than a 100 but only 4 feet long), the 96 is similar in water volume but no where near the length of the tanks mentioned. The one at your LFS
is also in a 6 foot tank.
