The plants will need some type of UV light to grow the tokays don't like light. So you will have to give them many dark places to hide plus all lights off at night. I like ceramic heaters for heat. I keep my ceramic heaters on all day and night in the winter for the tokays. I'm a beginner at the geckos but I think they are ok with most tropical plants. I would just say keep with a tropical theme. No cacti.
