This is only basic info about my breeding Horned frogs (Ceratophrys cranwelli) 
how it works in my care and my personal experience only. Other breeders can do it different.

 

When I started frogs breeding in early 2008, I cared more species of frogs, including horned frogs, darts and toads. These horned frogs fascinated me from the very beginning. I reduced the collection of frogs during the time and bought a breeding pair of Horned frogs 10 years later in 2018. I bred these frogs for the first time in the summer of 2021.

Housing:

Terrarium or plastic box with adequate ventilation for only one frog (30 x 40 x 30cm+) with natural peat and sand as substrate + shallow bowl with dechlorinated water. This type of substrate is changed every week or 2 as needed. Frogs are very susceptible to bacterial or fungal diseases, keep hygiene at all times. Many breeders use hygiene setups as sponge/foam as substrate. I use natural day light in the room.

Temperature:

Heat mats controled by thermostat and timer sockets.

Temperatures in the warm season are about 25-28°C (22°C at night)

in the cold "hibernation" season are about 13-18°C

I try to adapt and imitate changing of the seasons as they have in their original landscape in the pampas Grand Chaco-Argentina.

 

Warm season: April - November

Cold season: December - March

 

"Hibernation":

I hibernate only healthy and strong frogs in plastic boxes with adequate ventilation on a layer of moist peat substrate. In the dark cellar where is

13°C for 4 months without food. I feed for the last time about a month before hibernation, because their metabolism will slow down. I check the frogs every week or so and change the substrate once after 2 months. After hibernation I gradually raise the temperature in few days and start feeding the frogs. 

Rain Chamber:

About 2 months after the end of hibernation, I start preparing the rain chamber. It's a simple, big plastic box with a "fake" bottom, water pump and aquarium heater. Temperature of the dechlorinated water is about 28°C. After I place well fed couple (to prevent cross-attack) in the rain chamber male begins to very actively vocalize during the night and tries to catch female. I found hundred of eggs next day morning. If you do not find the eggs and pair is still in amplexus, try one more night. But then give the frogs a rest for a few weeks and try the rain chamber again.

Care about tadpoles:

I use big plastic boxes with 70l of dechlored water for about 100 or less tadpoles. The temperature is still about 28°C. I feed them several times a day with an adequate amount of frozen bloodworms. And changing all water every day. It takes 3 weeks to metamorphosis in my conditions.

Care about froglets:

Small froglets kept separately, in plastic cups with only little water and a wet paper towels. from the beginning, I feed them daily or every other day, and along with feeding them, I change their water and paper towel. I use trout fillet dusted with calcium and frog vitamins as a staple food for little frogs. I use large tweezers to feed them.
