One of the most beautiful frogs that is fairly easy to find in pet shops or at herp show it the Red-Eyed tree frog (Agalychnis callidryas) They are easy to take care of and easy to breed. Red-eyed tree frogs come from rain forests of Costa Rica in South America. They have bright red eyes and a almost neon-like shade of green with blue and yellow stripped sides with orange toes. They are excellent climbers. They are nocturnal and hide on the backs of leaves during the day and come out at night to hunt for small insects such as crickets. Males are much smaller than females. This species has been sucessfully kept by many herper's(is that even a word?) whit great success under the right conditions. This species of frogs do well together in community, but a pair of Red-eyes can be kept in a 10 gallon aquarium. But if more than 2 individuals are desired to be kept, I reccomend a larger tank such as a 20 high or larger, since they are superb climbers, it is better to have a tall tank so that you can put tall leafy plants in so they can climb and hide under. Once you have your aquarium picked out and ready to be setup, Get some plants at your local nursery which are suitable for tropical temperature and humidity, Ferns, Bromiliads and other plants with smooth surfaces that wont scratch or irritate the frogs skin. Take some aquarium gravel and put about one inch on the bottom of the tank then take a piece of air conditioner filter and place that over the rocks. Now you are ready to put some top soil in the tank, Pour about 4 inches of topsoil and then mold it into an interesting terrain. Find a small water dish such as a lab dish or a lid to a container that's about an inch deep. Stick the water dish in the soil till the soil is just before the rim of the dish. Mow you can selectively place your plants in your terrarium, place a large leafed plant over the water dish mabey about 6-7 inches above it. Next take some live moss or you can buy some of that dead stuff at the store, but I prefer live over dead because it looks much nicer. Cover the remaining soil with moss, be careful not to let any of the moss over hang into the water dish because it will drain the water real quickly. Now that your cage is set up, you need to decide on what type of lid you are going to use, you have a couple of choices. You can go with a regular all glass aquarium lid, which does not allow much space to put your arm in to attend to the tank, or you could make your own lid out of plexy glass and screen. The plexy-glass lid is a great lid because you can change it to change to humidity. To make the plexy glass lid, get a piece of 3/4 inch thick plexy glass big enough to fit on the inside rim of your tank. Next cut the center out leaving a 2 inch border around the sides, you can take tape and attach screen for the dry season or you can take tape and attach plastic wrap to increase the humidity as in the wet season.
Red-Eyes eat any type of insect that will fit in their mouth, crickets are to most easiest to get a pet stores, but you want to add a vitamin powder with vitamin D3 to the crickets. They will eat fly's, moths grasshoppers, and possibly other small frogs. You should try and feed you frogs every other day, watch them and see how much they will eat a night and figure out how much you should put in.
