Males tend to have more muscular forearms than females. Behavior Place your fire-bellied toads in the same tank to breed. If you notice that certain toads are plumper and rounder than others, these may be the female toads. Considerations Fire-bellied toads are highly social and should be kept in small groups. Nuptial pads help a male frog hold onto a female while mating. Compare the forearms of your toads.
Males tend to have a more slender appearance. If you notice a fire-bellied toad calling, which sounds like a croaky sort of bark, he is definitely a male. Because the toads only need the pads for a short time, they only appear during the breeding season. Fire-bellied toads breed in the spring, so if you have a frog tank, you will need to create artificial winter and spring environments for the frogs to cue their bodies to mate. Compare the forearms of your toads. Compare the sizes of your toads. Note that they each female can lay up to eggs at a time and they will hatch within a couple of days, so act quickly to sterilize unwanted eggs, which can be done by freezing or boiling before you throw them out. Nuptial pads help a male frog hold onto a female while mating. They will, however, breed, so only keep the eggs if you are prepared to raise the tadpoles, which would require another tank, and can find homes for all the resulting toadlets. Only breeding males develop nuptial pads, or rough dark areas, on the inside of their thumb, second finger, forearms and feet when they are breeding. This is another way to tell males and females apart. Males will hold females around the waist area and go into the mating position to mate with them. Considerations Fire-bellied toads are highly social and should be kept in small groups. You can examine the sizes of the toads, but you should look for the more definitive signs as well. Appearance Examine your fire-bellied toads for nuptial pads. Other Physical Characteristics Outside the breeding season, several other clues hint at gender, although none is as certain as the nuptial pads. It is difficult to determine male and female frogs apart because they are similar in appearance. Tips The calling behavior and appearance of nuptial pads are highly reliable in helping you distinguish the sex of your toad. Behavior Place your fire-bellied toads in the same tank to breed. The male gender of the species is the vocal sex during breeding season. Males tend to have more muscular forearms than females. Males have slightly better developed forelimbs than the females, more webbing on the hind feet, more knobby backs and somewhat slimmer physiques -- females tend to look chubbier. The task is not an urgent one - the fire-bellied toad is a sociable species and no combination of the sexes is likely to fight. To tell the sex of a frog, you need to own more than one so that you can watch their interactions and behaviors. Identify which male toad is making the noise.
