Here's my current mantis set up.  I'm only running a local species called the Chinese Mantis (Tenodera sinensis).  Top right is hatching house, contains the ooths and is free of random stuff to make it easy to get them out.  Underneath it is an ancient adult female.  She's starting to falter and likely will end up as an entropy piece once she's finally gives up the ghost.  The small class terrarium is newest hatch of babies.  Not all that many hatched so they got a small tank.  The large terrarium was series of hatches from the same week.  They get their fruit fly breeding dish help prevent cannibalism.  They hatched a few weeks back and have already shed once.
