Which darts can be housed together?

Mixing species of dart frogs aside from aggression can lead to hybrids which are sterile. Although i prefer not to admit
it, there are very few dealers out who will sell sterile frogs.

We've seen zoos and aquariums mix species but their vivariums are purposely
enormous and densely planted to avoid any confrontation between the frogs.
