I have read that expression of pearlscales is highly affected by environment. I have now had two different pearlscale pairs produce babies that never expressed it in my care. But babies from the same batches sent to other people did develop them.

I would really like to know what environmental things affect the expression of the pearlscales so I can make any necessary changes so my offspring to develop them.

Is it lighting like the half blacks? Or what? what are those environmental influences? I have read about them existing on many sites, but not a single site say WHAT those influences are!! haha please help!!

Thanks!
