Thankyou for your comments. I think the male may be the issue, although he is only a few years old, was wild caught but healthy and looks great. Separating him is worth a try. This colony produced dozens of healthy eggs in the past, but now I get soft, flabby, slugs... I removed a couple of females that I suspect were fighting. I was shocked to find two dead females, one with an avulsed tail the other just dead, apparently from stress. This never gets boring...and when I think I have it figured out, I get humbled...Thankyou.
