Where do Dart Frogs lay their eggs in the enclosure?

[Philsuma]

Depends on the various species. All must have a constant high humidity spot. Some utilize leaf litter, some broad-leafed plants, some film cans and finally, some on clean flat smooth surfaces under a cocohut for example. That takes care of the egg deposition site and then the larvae gets transported to water - could be small pool, bromeliad or another film canister with some water in it.
