I detect things getting a little slow around here.... or is it my imagination?

After researching African Night Crawlers I became so intrigued I purchased some for the heck of it last year (May/June timeframe). The internet reputation that precedes them says they are nearly the size of the earth dwelling Canadian NCs and probably the most voracious eaters of the composting worms which (one could have then logically deduced) leaves behind giant sized castings "the size of rice grains". They like it warm and will continue to compost at much warmer temperatures than the "other guys" (red wigglers and Euros) but will perish at temps below 50F. They also prefer bedding to be drier too.

I have Reds, Euros and now the Africans. I should also mention that the Reds and Euros are kept mixed together in several 30 gallon worm bins stack in the garage, while the Africans are kept separate by themselves in two 30 gallon worm bins. What I've experienced with the Africans thus far has been a mixed bag. True, they are the big guys on the block... yet in general they are smaller than the common earthworms in my backyard, however the very biggest of my Africans can be as large as some of the earthworms I have found in the garden. Though their castings aren't quite the size of rice grains (we eat a lot of Basmati so maybe that's it), they are still quite big when compared to the "other guys" poop. Voracious eaters? Yeah, I'd say so, especially when it is warm, like above 70F... in a head-to-head with the "other guys" its no competition but if you consider a comparison weight-wise now that might be closer. Warmer bedding temps (up above 80F) only make these guys eat more, this is true however at the other end of the temp range, I've found they do NOT die at under 50F... in fact, they don't even die at under 40F... I measured bedding temps this winter at down to 37F and the Africans pulled through just fine without issue, they were healthy though seemingly without any appetite at all, whereas the "other guys" never quite stopped eating. Today with the bedding temps nearing 50F, the Africans are up and about showing themselves and hungry... I just got through feeding them.

Anyone else raising these Africans? What's been your experience? Their mythical reputation vs what you've found to be the reality. Heck, even if you haven't raise Africans, what are your thoughts? As the temperatures warm and the worms become more active, I'd kinda like to see this forum also increase in activity.
