Housing
Cuban Tree Frogs require a tall aquarium (at least 25 gallons) with lots of plants (Monstera, Philodendron, Ficus, and Sansevieria are good choices), a shallow bowl of DECHLORINATED WATER, hollow branches, cork bark, etc. Non-Chemical potting with moss covering it can be used as a substrate. Never use cedar or pine shavings (toxic), gravel (abrasive), bark or sand (abrasive and ingestible) as a substrate! Mist with DECHLORINATED & STALED water (add dechlorinating drops as directed and let sit over night) a few times a day. Clean the entire enclosure once every month or so with hot water and no chemicals.
Temperatures
Upper 70s to low 80s in the daytime and at night remain in the mid to lower 70s. This can be accomplished by using under tank heaters or a ceramic heat emitter (be sure the frog can’t come into contact with either source and that there is a layer of substrate between the heated glass and the frog). Hot rocks/sticks/caves should not be used due to the fact that they can cause thermal burns in frogs and other animals.
Diet
Crickets should be the main food source. Feed the crickets exotic fish food or cricket feed for at least 24 hours before you feed them (the crickets) to your frog. When fully grown Cubans can eat larger prey such as baby mice, but this should be a sporadic event. Be sure to get bugs from a pet shop or other source rather than collecting them from the wild where they may have been contaminated with poisons and/or diseases. Remember to remove all dead or uneaten insects/food items everyday.
Health
If your frog is cut or burned by something in its cage, remove the object and call a vet before applying any kind of medication due to the fact that some can be lethal to your frog.
Fungal infections are very common in tadpoles and younger frogs. They look like inflamed areas of the skin surrounded by whitish threads. In its early stages, it can be treated by immersing the frog/tadpole in a 2% solution of malachite green or Mercurochrome for five minutes, repeated again after 24 hours. A veterinarian should be called if the infection does not clear up.
Red leg is a common disease in frogs caused by bad husbandry. It causes small ulcers, hemorrhages, and reddening of the skin around the belly and underside of the thighs. The infected frog should be kept warm (85 F) and immersed in a 2% solution of copper sulfate or potassium permanganate.
You should always at least consult a veterinarian if you think there is something wrong with your frog!
