So, I found well over 20 dead but that is not surprising, considering doubletail IS a deformity in all actuality. Most of the dead ones pulled had spine deformities, or just were not strong enough. However a good number still remains, which is great.
As for the MW and BW cultures, the bloodworms are already teaming in ONE container, building up in the second container, and the large container they'll take longer to progress but there is some movement. As for the microworms, they are working on it ;)
