This study evaluated space use and activity of individually housed Phelsuma guentheri to formulate recommendations for environmental enrichment. Gecko location within small (0.03 m 3 ) and large (0.22 m 3 ) vivaria and substrate use data were collected over five 24 h periods. Thermogradients within each enclosure type were determined by measuring temperature at various heights. From these data, geckos' space use, activity cycle, and substrate preference were calculated in relation to temperature changes and photoperiod. Geckos did not utilize their environment uniformly. Heavily utilized locations contained cage furnishings or hides. Geckos avoided the use of vertical glass walls. Thermogradients were not actively utilized; however, when given the opportunity, geckos would orient towards natural sunlight. Enclosure size did not affect activity cycle, which was nocturnal with crepuscular peaks. Recommendations for enclosure improvement include provision of more furnishings and hides at different thermal levels. An alternate focal heat source other than UV light is recommended to provide warmth without light. Larger enclosures may encourage more uniform use of available space. Transparent glass may not be an appropriate substrate for these geckos. Once recommendations have been implemented, a similar study must be conducted to assess benefit. © 1995 Wiley‐Liss, Inc.
