Frogs lay eggs in a gelatinous mass. Take care to remove eggs from the enclosure gently. Cover the petri dish with plastic wrap to ensure that the eggs do not dry out. It may be necessary to add water to the petri dishes containing eggs. The eggs should always remain 80-90 percent submerged in water. Be careful not to spray the eggs when getting them moist because frog eggs are very fragile and are not meant to be misted with water. If the eggs are misted, a water droplet can fall on them and they can become concaved and die. Any eggs that become discolored, (usually grayish) are infertile and should be carefully removed with a razor blade or plastic spoon. The eggs will collapse when the tadpoles are ready to emerge, usually in 1-2 weeks. Sometimes the tadpoles need assistance exiting the gelatinous mass. Gently remove the gelatin from around the tadpole and lightly spray the mass with water, or using a razor blade to cute the mass until the tadpole is free.
When the tadpoles are free, separate them into their individual containers. Many poison arrow frog tadpoles are carnivorous and should always be reared segregated from other tadpoles. Be sure to color code the tadpoles’ petri dishes and containers so that you can track the parentage of the frogs.
In the wild, the males (and sometimes the females) moisten the eggs by producing mucous. When the tadpoles emerge, the male frog, in most cases, transfers the tadpoles onto his back and into a suitable water source. Males (and sometimes females) guard their eggs.
