All of these exhibits are currently being combined to make a single exhibit for a single Rhinoceros viper and a single Puff Adder. Below is a "demo" that shows a similarly renovated exhibit for a Terciopelo.
Scratch that last post now, the top middle exhibit now contains a Nelson's Milk Snake, the bottom left has a Puff Adder, and the bottom right has a Rhinoceros Viper. The top left does still contain a Green and Black Poison Dart Frog.
The species list for these exhibits are
Top left: Green-and-Black Poison Dart Frog (same as last year)
Top Middle: Yellow Pond Turtle
Top Right: Same Day Gecko
Bottom Left:Yellow-tailed Cribo
Bottom Right:Northern Copperhead
