Lopéz, peat is a good substrate, although you have to make sure is sterilised. You can buy it from quite a few pet shops already sterilised, but I always pop mine in the microwave for a couple of minutes, just to make sure. Peat seems to help keep the humidity high and looks much better in a tank along with silk plants and half a plant pot. I try to make my set ups resemble the area the spider would be found in...........well almost. I have a coulpe of crock skulls in two of the tanks. Nothing like watching them crawl in and out of the eye sockets
I am also tempted to go for a Cobalt Blue, the problem is that in order to see the colours shown in that rather nice pic you posted, the lighting would need to be just right. Most of the time, in normal light they look black.
