We are starting to see some here in arizona, we get vietnam shrooms and Z/P colonies often but the sps less often as it has been more hit and miss(per the LFS I go to) I do have a nice chunky frag of green tenius with white polyps that has been doing well for over a month now, but we know with SPS that is a very short time period.
I had a thinner branch green/blue that came in the same shipment and it STN'd over 4-5 days, couldnt figure why since all other sps around it was fine.....I blame it on how finicky wild caught/Nam SPS can be but who knows.
