The ebenaui I have I use a coco fiber(bed a beast) sand and organic soil mix(70%coco,10%sand and 20% soil) for mine. I kinda go over board on that the coco fiber by its self will work but I find that the plants grow better in the mix. They like corkbark (the males will hide in it)and lots of plants in the tank. I use pothos and some bromiliads(SP?) with mine. If you get with Deven (Terra5 Designs) I am sure he can recomend lots of great plants for you. That is where I go to get good plants. I dont have any pics of the tanks right now but when I get back (in December) from Iraq I can take some if you want to wait that long!
I would not get the U.Lineatus just yet and as far as the phantasticus I would wait on them as well. They both dehidrate FAST and they will some times crash HARD and fast if there is any mistakes with them. I have 6.6 U.Phantasticus and 1.1 U.Lineatus and I think that the U.Lineatus are one of the most dificult Uroplatus to take care of. Because they dehydrate so fast I have to "shower" them once a week to keep them hydrated.
The U.Phantastuicus are good and hardy once they get set up and can be kept simular to the U.Ebenaui but with a few additions. They will need to be sprayed more and I would recomend a ultasonic humidifyer(SP?) I got min at walgreens and I love it. They are a cool mist and they woork wounders. And thay are cheeper than the exo-tera, they are cool mist not the 85 degree ones, and they last longer too.
I know that the U.Phantasticus look "cooler" but trust me they U.Ebeanui are so much more fun to watch they are so active and funny! Not only that they are much stronger geckos as well.
Hope this helps!
