It's really hard to tell the sex of these species. One of my first toads is very obviously male. He is the only toad out of my five that has a constant call and amplexus all the "females", however just today I noticed two of my supposedly female frogs (who were taken advantage by my male on multiple occasions), are exhibiting the same actions. I'm not sure if this species care about sex when they mount, of it they just mount anything that moves. But from what I've seen, my one male and four females may actually be three males and two females. And I still can't be certain.
