However, if you have adult frogs that are well fed, then it is possible to keep groups of them together safely. The first step in breeding them is to determine whether or not you have specimens of both sexes.
Females grow much larger than males, and are silent.
Males will call, often after being sprayed with water. In fact, a persistently calling male can drive you to distraction if you have to share the same room with him. If you have an adult pair in good physical condition, you need to put them through a cool, dry period to get them ready for breeding. A water bowl should be available at all times, however, so the frogs can seek it out if necessary, even though they'll probably just go under the moss and stay there. The temperature in their enclosure should be reduced to approximately 70 degrees Fahrenheit.
