These do great in my dart frog vivs, 65 to 85 degrees.
Upper level:
Dendrobium oligophyllum
Oncidium croesus
Bulbophyllum Kalimpong
Cirrhopetalum tingabarinum
Bulbophyllum fascinator
Mid level/Lower levl:
Dracula lotax
Masdevallia herradure
Masdevallia "Glowing embers"
Pleurothallis allenii
Pleurothallis microphylla
Restrepia brachypus
Restrepia muscifera
Currently experimenting with:
Bulbophyllum lasiochilum
Bulbophyllum odoratissimum
Pleurothallis restrepioides "dragonstone"
Pleurothallis fastidiosa
Pleurothallis megalops
Restrepia antennifera
Masdevallia "Angel tang"
All are recent additions to vivs, too soon to tell whether or not they flourish, but I think they will do just fine
