Billbergia Hallelujah is a medium to large-sized bromeliad that is perfect for a clustering in an 18x24 or 24x24 vivarium. They get at least 16-24 inches tall, but usually stay under 18 inches. This bromeliad has a steep cup that is purple and pink with green flecking. Color upon receipt may be slightly duller due to growing in lower light conditions. 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. These are to be planted in well draining substrate!
