Thanks for your feedback, Lynn.
I find that some of the semp arachs were not thriving as well in the semp bed, so I pulled them out and put into a separate flat. Then I slowly reintroduced a variety at a time but put them behind a rock or in an area where the sun hits last during the day. This all helped and I am now contemplating being more selective about which fuzzy or ciliated or hairy (sorry about the old names to describe) I put in the bed so that I don't buy the ones that don't thrive that well in the bed.
