normaly if both parents are BB than the babies should be BB. Maybe one parent is just a BhB that is realy high coloured or the baby just has a bit darker colour?
You can not be 100% sure that both adults are Blazing Blizzards if they produced a normal banded baby. If they produced a normal banded baby, I am 100% certain that they are not both Blazing Blizzards of the same albino line.
It sounds like you hatched a light colored Blizzard het Tremper & LV, and a normal het Tremper & LV--I'd bet the parents are both Blazings, ones a Tremper and ones an LV
Either way, though, if both parents are Blizzards, regardless of what albino strain they are, shouldn't all of the babies be Blizzard het LV and Tremper (if, indeed, one parent is Tremper BB and one LV BB)???
