I have an old ExoTerra Nano tank/tall (8"x8"x12") which I would love to put something in. Tarantulas and bugs are fine, it used to house a preying mantis which passed after laying eggs (they unfortunately did not hatch). Give me your ideas! I was thinking maybe some species dwarf tarantula? Maybe another mantis (if I get another mantis, I think an orchard mantis would be awesome).
