Looks like a form of Epipedobates bassleri to me (I could be wrong). If you would like to see more pics of them go to http://www.livingunderworld.org/gallery/photos/anura/dendrobatidae/epipedobates/bassleri/
:I've got a breeding group of 6. Bought them in Germany from an Hungarian guy. He said they are pictus but I don't think they are. They don't look the same and they sure don't sound the same. Some people think it could be femoralis. I go for hahneli for know. But I would sure like to have some more information. Does anybody know where in Peru they come from??
