Hi yes i had this one about 4 years ago with my Chromatopelma cyaneopubescens, it never had the difficulty walking/climbing thou... what i suggest is you clean your tank very well and every artefact in your cage... and give it a large water dish, what you will notice is it will drink and the white stuff will get washed off and your T will be ok... if it is the same thing..
Looks like you have a Male Poecilotheria fasciata in the pic... if you were wondering :tongue:
