This may be where I originally saw it. These two snakes came from Nick, and were from a first generation cross that, as he put it, were at the time the most distant related pure IJ granites made - period. I'm sure that is not the case anymore though :-). I'll check his book out in my Library when I get back home and see if I can find it there as a reference. I know from talking with Nick though back in 2012, he did a lot of breeding pairs in CB70 tubs. I followed this advice for grow out and it worked well. But I am much happier having them back in an arboreal setup with ample room. Adding vegetation soon for this pair.
