Mist the axils. Keep them full when the frogs have tads in them. They should always have a little reservoir of water. I am speaking of the Neoregalias, and some others, but not for the whole bromeliad clan. The Bromeliaceae, the pineapple family, is diverse. We mosty use the epiphytic types that grow on trees and hold water in their axils for themselves and dart frogs. Neoregalia, some Vresia, are usually small enough or can be contained in vivariums. The Tillandsias and Cryptanthus are small, decorative, but not useful for frogs that like leaf axils for breeding and hanging out in. Many others, like Aechmea. Billibergia, Guzmania tend to grow too large for a small vivarium. (Between 10 and 135 gallons.)
