I'm planning on building 8x2.5 ft enclosures for them in the (near!) future. The female will probably out grow the 4x2 in a year, the male may be ok for a year and a half. Basically, they'd just be bigger versions of what I just built. And I'd probably do a triple stack again. I'm toying with the idea of getting either an albino burm or albino green burm (maybe patternless) female and trying for Bateaters het for albino, or Green Bateater Hets. Of course, I'll also be breeding these two hoping for SuperTigers.
