Sometimes they just have problems molting. No matter what you do sometimes this occurs and you can't help. Some spiders are repeat molting disasters that happen over and over again. I had one that had problems every time it molted until it finally got completely stuck. Just trying to help it is all we can do.Scratch the Suggestion of plenty of humidity. Chromatopelma cyaneopubescens are arid species. High humidity has been known to kill them. Just feed and water it properly. The moisture it needs to molt is within the spider, not the air.
