Been a while since I've updated and a little bit has changed. First off, a somewhat embarrassing discovery, it turns out that it appears as the nymphs have grown, the species have changed on me I had a couple deaths due to late food arrival and have 4 mantids left.
1 adult female shield mantis
1 presub (?) male widearm.
1 presub female african
1 prepresub female african
They're doing fine now, being fed exclusively on lobster roaches. Unfortunately the die offs from lack of food mean I need to obtain a fresh adult male shield mantis in order to mate her. In a couple of weeks I guess I'll start looking around.
