Thanks for the advice, Mark. I have 3 juveniles (A. bit  Umudike)that have
not sexed out yet,
but am hoping for a trio, reverse or otherwise. I had 30 plus eggs sent and
was able to
hatch out 9, but over one evening, I was down to the three. My water is ph
7.5, GH 11, and
KH 3 (Huntsville, city water). Slightly harder than yours, but adequate. I
suspect predation
 (the remaining 3 looked quite robust, and still are) but am wondering if
water quality was
another factor: changewater was dechlorinated tapwater at least 2 days old,
and I changed
 50% everyday, sometimes every other day. Had I cut that down with seasoned
tankwater,
it might have brought on better success. Going from Maine wellwater to
Huntsville city water
has been an ongoing (as you say) " trial-and-error" experience.
