the only problem i see is depth. the width and height are fine but it looks to have now were near enough room for a adult to turn around comfortably you need at least 18 inches in depth for an adult. this will be fine for about the first 4-5 months of life. but you will need a larger enclosure. you could build your own custom one. just search in google crossfire enclosures. instructions will pop up for you.
I agree for a hatchling to small juvie it will be OK but as for adults even a 55 gallon tank is too small, they are not deep enough for an adult to turn around comfortably. I kept adults in tubs that are 3' x 2' x 2'
