Re: Tree Frog Enclosures
You would need a twenty-gallon tank with a screen top. With treefrogs height is better than length, so a standard twenty is better than a twenty-long. If you can find one, a twenty-extra high, is even better and uses the same size top as the ten-gallon aquarium.
You will also need a water bowl. I use dog or cat bowls as they are much cheaper than "reptile" bowls. You should mist the frogs down once a day, so you will need a spray bottle. You can either use dechlorinated tap water, spring water, or distilled water to spray your frogs. However, do not use distilled water for your frogs primary source of water.
I would use white paper towels as a substrate for a while. They are cheap, easily replaced when soiled, and will allow you to monitor your new frogs health a lot better than other substrates. You will be able to spot new fecal samples and then you be able to bring a fresh one to your vet to be examined for gastrointestinal parasites. After a period of 30 - 60 days you may change the substrate to ground coconut shell or sphagnum moss or a combination of both. Do not use gravel ever! It can and will lead to intestinal impaction and that will lead to death if left untreated.
You will need some cage furniture. This can be vines and/or branches to climb on and broad-leafed plants to hide in. You can use artificial plants if you like. Any branches you use from outside should be sterilzed by baking in an oven for an hour or so between 150 and 200 °F. That will kill any nasty critters living within them.
