Curtis,
The pen looks great, mine are still under a foot of snow,lol! I saw those waterfall ponds at Menards and Lowes too and thought they would be good in pens, but they are a bit pricey, but how can you pass up the clearance deal that you got, nice score, I should go check my local Menards and Lowes.
Just a suggestion you might make sure they can get traction to climb out of those waterfall ponds even though it slopes on the one end, it may get slimey and slippery with algae, maybe adding gravel or flat piece of wood, don't want any drowned boxies. Of course it will be easier to thoroughly clean periodically without the gravel. Looks like you have a nice variety of habitats and different substrates, I need to add more variety to mine.
