It is also important to provide proper ventilation in the enclosure while keeping proper humidity. Unlike most other day geckos Phelsuma barbouri requires a horizontally oriented enclosure. Fine grade well-washed orchid bark may also be used as a top level substrate. Both vertical and semi-horizontal bamboo stalks should be provided for climbing and basking. The semi-horizontal bamboo pieces should be placed near the fluorescent and incandescent lights for basking.
Cork bark makes an excellent wall covering and also provides attachment points for epiphyte plants.
It is also important to provide plenty of hiding places for day geckos which will help to reduce stress. Most species of day geckos require a relative humidity of 50 to 85 percent that can be maintained by misting the enclosure several times a day. Plants and proper substrate are important in maintaining required humidity levels. Several full-spectrum fluorescent lights should be placed at the top of the enclosure. Vitalights or other reptile fluorescent lights that produce small amounts of UVA and UVB lights may be used.
