Film Canisters are a must have for anyone breeding poison dart frogs,
especially thumbnail dart frogs. They provide a great place for your frogs to
hide, hydrate, and breed. Using canisters makes it far easier to see the frogs
and their young, and, more importantly, makes it far easier to remove them from
the vivarium for rearing.
In the wild, these frogs lay their eggs in bromeliad axils. This Bromeliad
Canister Holder mimics this in captivity to encourage breeding.
