PB marble fry....

[Mugwump]

Some of these are pretty dark...M/M pb/pb ...and I swear that I'm seeing expressing HB's in there too...but how can that be???....I'll get a better look as they grow tho..... ..it's likely just tight marbling patterns and will spread out as they get bigger.....

Yes, they are F1 siblings....but I'm sure what I'm seeing....they're so dang fast that even a magnifying glass doesn't help a bit....it's likely tight marbling at this stage.....we'll know better as they grow some more...

They're awfully young to start expressing HB.  It would be cool, though.

I can see marbling and some other markings already too....
