Distribution and habitat

The Cranwell's Horned Frog Lime-Green is a color morph. The range of the diurnal to crepuscular Cranwell's Horned Frogs is in central South America, from Bolivia through Brazil and Paraguay to northern Argentina. They inhabit rainforests up to 700 m above sea level, where they usually lie in wait for prey, well camouflaged in the ground except for the top of their head and eyes. They always stay near small bodies of water.

Maintenance

For 1 animal, the minimum terrarium area is 3,600 cm² with a minimum effective height (measured without substrate) of 40 cm. This corresponds to a floor space of e.g. 60 x 60 cm. Keeping several animals in one terrarium outside the mating season should be avoided, as the animals are cannibalistic.

They need a loose, diggable substrate of a peat-sand-forest soil mixture (terrarium soil) of 15-20 cm depth as well as foliage, bark pieces and roots as hiding places. Potted plants (e.g. bromeliads, philodendrons, syngonium) that can be easily removed for cleaning as well as mosses are advantageous. A bathing opportunity must be offered, but the water level should not go above the animal's nostrils, as they are poor swimmers and could drown. Once a day, preferably in the evening, the inside of the terrarium should be finely sprayed with water (humidity), but a rain or mist system is better.

Temp. day: 24-28 °C

Temp. night: 20-22 °C

Humidity: 60-80

Thermostatically controlled floor heating is recommended. The lighting duration must be 10-12 hours depending on the season. Daylight fluorescent tubes with low UV content are ideal.

Diet

Their diet consists of cockroaches, grasshoppers, crickets, mealybug and wax moth larvae, slugs, earthworms, and occasionally young mice, according to their size. They will try to eat anything that moves and fits in their mouths. Feeders that are too small are often spurned. Adults should be fed every 3-5 days, younger animals more frequently. It is important to add minerals and vitamins regularly (e.g. by dusting the feeders). The quality of the feeder insects can be enhanced by the addition of overripe fruit and honey water

A varied diet promotes health and prevents deficiency symptoms.

Reproduction and breeding

Males remain significantly smaller than females.

Summer dormancy is a prerequisite for successful breeding. In the following rainy season, the female ready to spawn is taken in the mating grip (amplexus) by the male and she lays over  500 eggs in spawning balls freely in the water of temporary pools. The larvae hatch after one day and are cannibalistic like the parents. After about 30 to 90 days the transformation (metamorphosis) is completed and the young frogs leave the water.

Important

For summer dormancy (dry dormancy), the temperature must be lowered to about 15 °C and the humidity reduced. They form a cocoon and burrow into the ground. During this time they must not be disturbed or fed. After 6-8 weeks, the temperature is raised again, humidity is increased to 80-95% (rainy season) and the frogs finish their summer dormancy

The terrarium must have good ventilation without drafts and meet the species specific needs. Measuring devices, such as thermometers, hygrometers, etc. are necessary. The lighting has to correspond to the species-specific day-night rhythm and has to be placed in such a way that the animals cannot injure themselves. The terrarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Special attention must be paid to thorough hygiene and impurities must be removed regularly.
