Second Batch Of Bn Fry Completely Different Colour To First. Question

  1. Littlebudda Well Known Member Member

    I’ve never had this before but my first batch of fry were all very dark the same as the parents. Now my second batch are really light and I have a couple of fry that are literally half dark (head to dorsal) and pure white/see through on back half (dorsal to tail).

    Has anyone had this happen before?

    Could not get any pics of the half colour fry but here is a pic of the colour of the others.

    First batch of fry dark colour

    Well, I don't know too much about breeding them, but I know that with many animals including humans, it's a random shuffle of which genes are expressed. My molly fry hardly ever look the same or close with each batch and I've only got one of each gender as the breeders.
    Do you only have two adults?
    It coulld just be genetic vomit. Not that they're bad or anything, I just mean, like, BLEH HERE'S SOME RANDOM OFFSPRING.
    I'm not helping. LOL.
    They are however really neat. I like the second batch.

    They are likely just mutts, your common colors may throw marbles (which is what the splotched looking babies would be considered) just because they are "mutts" (though for bristlenose in the hobboy this is a misnomer, as most have been crossed to produce what we have in the hobby) you would have some weird genetics play out, this also means the parents are likely siblings or half siblings (or something similar to that, they could be father/daughter, mother/son, grandparent/grandoffsring, etc..) to produce recessive trait fry.
