I went to Amphibian Management School back in February. Yes, that’s really a thing. Frog populations have declined rapidly over the last several years due to a number of factors – habitat destruction, globalization, climate change, pollution, etc. In the US alone, populations are declining at a rate of 3.7% per year, so an annual training class to help zookeepers care for these animals is very necessary. One day I’ll get my act together and share some cool things I did and learned, but today isn’t that day. Today is about sharing one thing.
Our curator told me that we’re acquiring some Tiger-legged Monkey Frogs (Phyllomedusa hypochondrialis). I have never worked with this species before, but I am pretty stoked. Why wouldn’t I be?
We aim for mixed-species exhibits wherever possible because animals in captivity often do better if we can mimic their eco-system. Imagine being alone in the world – no birds, no insect sounds, no fragrance of flowers or trees. Boring and stressful, right? I even introduced some isopods (pillbugs) and native plants into a milk snake enclosure, and he has been more visible and less jumpy.
We just happen to have a snake that cohabits the tree frog’s ecosystem, so it was my job to create an exhibit that could house both while being visually appealing. Thank you, Amphibian Management School! I got this!
So the exhibit itself isn’t the most attractive, but I can work with it.
We need a good base. The exhibit needs to be heavily planted. Here’s the dilemma. The frogs need to be sprayed heavily every day, and plants like water, but not TOO much water, or their roots will rot. The solution? A false bottom. The frogs get their spraying, and the extra water has a place to go.
Take a piece of plastic egg crate (it’s really plastic mesh) and cut it to the size and general shape of the enclosure. Then take some pieces of PVC pipe. Their length doesn’t matter at all, just their diameter. The job of the pvc is to hold the mesh off the bottom. Don’t stand the PVS straight up, or they will get clogged with dirty water that you can’t get out.
The water under the exhibit will eventually build up and soak the substrate unless you have a way to get rid of it. Solution? A stand pipe. I can run a piece of flexible tubing down into the stand pile and drain out the extra water.
Cover the egg crate or mesh with wire screen. This step keeps your substrate (dirt) from dropping straight through the mesh. It’s very inexpensive. Also, this is the step I forgot to take a photo of. Secure the mesh to the screen with zip ties for added peace of mind. I zip-tied mine every which way from Sunday, just to be on the safe side!
Add your substrate. Frogs breathe through their skin (some species don’t even develop lungs at all), so any toxin in the environment goes straight into them. So get the organic stuff. There’s a mix called ABG, after Atlanta Botanical Garden, after the facility that perfected it. People have tweaked it to their own needs. I was limited to the items on hand, so I used equal parts milled sphagnum, crushed peat, and long-fiber moss. Most people also add charcoal (like, a bag of Cowboy charcoal you get at Lowe’s – simply crush with a hammer), but I didn’t have any. I dumped everything into a trash can I use for feeding snakes and wetted it down thoroughly. WEAR A MASK. This stuff is dusty, and you’ll be sneezing brown for days. Don’t ask how I know.
Now’s the fun part. Add some branches for the arboreal snake. He is one that never comes down to the ground, so the more options you can give him for hanging, the better off he will be. Let him choose if he wants to be higher, lower, covered in plant leaves, etc.
Add the plants. This is my favorite part. I LOVE plants almost as much as I love my animals. I made a trip to Stanley’s Greenhouse to find some lovelies to put in my exhibit. I used a Bird’s Nest fern, a hybrid fern, many varieties of Elephant Ear, a tiny little Philodendron, Lady’s Slipper, and some vining plants. Go pesticide-free for frogs.
I am very pleased with it. Time will tell if the Emerald Tree Boa will beat anything up. What does he think of the set-up?
If you have any questions at all, don’t hesitate to ask. If I can do it, seriously, anyone can! What have you done that you didn’t think you could do?
