I added a small pond for them to breed, at the moment 2 are lached onto eachother. Another male is calling like crazy. I believe the 4th frog is a female, I'm not sure at this point. It was dangerously skinny when I bought the poor thing. (long legged spiders got her eating again)

I just added a placo to the water section to take care of any algea, that won't prevent the female from laying her eggs will it?

If anyone has any tips for breeding I would appreciate the help being this is my first putting together a tank like that.
