Hey, I have 5 phyllomedusa hypochondrialis as well. I think I have 2.1.2, but I may have 4.1 As of now, mine are seperated in quarintine for their 3 months, but they should be out any time now. The frogs will go in and out of amplexus for a while, but you need to have plants with soft bendable leaves in there for them to lay their eggs on and wrap the leaf around them. Pothos is a good plant for that, maybe bird's nest fern as well. I'm going to be setting up a permanent enclosure for them to breed soon.
