spiny tails are probably one of the best geckos to watch. mine are nearly always out on sticks and things so it wouldnt really mater if you put a few things to decorate the cage. they arent too smaller gecko either which makes them easier to handle than things like bynoes. bynoes are alright except theyre really fast (not that scittish just fast) and small. i'd go a spiny tail gecko if i were you. you can make a really good looking setup with them and you can watch them in it. i'll post a picture of my geckos enclosure in a minute.
