Blue morph chondros are not the extreme rarity they once were, and hormonal blue females especially are not uncommon these days.  "True blue" chondros (those having blue coloration as part of the ontogenic color change and not induced by pregnancy) are still one of the most desirable and least available of the designer morphs.  Males are highly sought after.

Blue Frost represents a big step forward in the development of blue morph breeding. The product of blue parents, he changed from a dark brown offspring into a magnificant blue
animal at a younger age than any chondro I have observed. Most blue chondros continue to develop blue coloration as they mature... if this male follows that pattern he may well be the best blue chondro I have ever seen.
