Your setup is lovely but the vertical orientation is really more appropriate for oophaga or ranitomeya. I wouldn’t recommend either genus as a beginner but that’s not to say it’s impossible. As far as the oyapock locale goes they are small but bold. They are considered tough to breed though and I haven’t personally seen one for sale in a few years. Mine is always out and about but she e makes no use of vertical space. Some of the larger tinc locales will climb but it varies among individuals. One of my “Patricia” climbs fairly often and the other does not. A single smaller tinc locale will probably be your best bet.
