Neoregelia Ardie is a medium to large-sized bromeliad that is perfect for a centerpiece in an 18x24 or 24x24 vivarium. They get about 16-18 inches in diameter, but can be successfully worked into 18x24 enclosures. This bromeliad has a bright white center with green margins on the leaves. Bromeliads are epiphytic and will send roots out in order to attach to other plants, rocks, or backgrounds. Bromeliads also hold water in their leaves, providing deposition sites for tadpoles. For this reason, we do not recommend planting this Bromeliad in the substrate; if they are watered from the bottom and top, the core can rot. Many dart frogs, especially Oophaga, rely on these plants (and film canisters in captivity) for breeding. Bromeliads form pups from the mature plant and will clump together. Please add fresh water to your bromeliads at least weekly, and allow them adequate ventilation. If you do not have ventilation, we do not recommend keeping them fully filled with water.
