Can you house a red ackie monitor in 40 gallon tank?

A red ackie monitor (Varanus acanthurus) should not be housed in a 40-gallon tank. This species of monitor lizard requires a much larger enclosure to accommodate its size and activity level. A minimum enclosure size for an adult red ackie monitor is a 4'x4'x6' (1.2m x 1.2m x 1.8m) enclosure.
