Funny you say that. The only one who likes to hide is the versicolor. In the previous cubes they all had plants in them and every one of the Pokies stayed away from them. My adults even webbed them almost solid to the ground. When I put the cork background in instead they all began to feed regularly and almost instantly. Some of the slings were very picky eaters with the plants in there. Since the bark, no problems at all. Maybe its coincidence, lol. Maybe the bark gives them the security of thinking they are actually on the tree. No privacy with 4 clear sides but the bark darkens it and gives them something to climb up. I am gonna try the plants again though, when they move into the next size enclosure.Nice looking containers. They all look like clones. Maybe ad some green to spice it up? Give them places to hide?
