I have a 77 gallon tank that I recently took out. It measures 51.25" (L) x 15.25" (W) x 22.75" (H). The tank is made of 1/2" acrylic, has euro bracing, and a compact overflow on one of the short ends. The tank was setup as a see through in-wall so the overflow was designed to be shallow to reduce view obstruction. No crazing but has some scratches that could use some buffing.
