what cage is better at keeping the proper tempature level for water dragons a reptarium with a screen cover or a glass cage 8)
Glass is almost always easier for keeping proper humidity and temp for almost any herp. It can be done with a screen enclosure but glass will be more sturdy. I would recommend a screen top though to allow air exchange and excess heat to escape.
