Have you thought of having a combination of say water skinks and tree frogs. The water skinks will be active in the day and the tree frogs active at night. If the enclosure is large enough, you could even keep small water dragons for a period of time. Once they get to big you can accommodate them out doors or sell them and purchase some more that are small.
Whatever you get, you need to be able to meet the power bill for running light and heater, summer AND winter! And you also need to be able to meet the cost of feeding the animals their appropriate food. There is NO such thing as taking cost shortcuts with either of these things – just sickly to dead animals as a result. So do your research and then do your sums. Hopefully it’s a goer and you can enjoy your animals for many years to come. Here’ hoping!!!
