Thread: Bulgarian Green Variations

  1. #41
    Back to the Bulgarian Greens.
    I kept back about 15 from Batch #2 as potential breeders, most I selected were classic "BSP's" as both parents were homozygous for pb, all are pb/pb.
    I also kept a couple of lighter ones and a few darker individuals, thinking that they were D/D, recently the colour of these has intensified and to be honest I'm now no longer sure that these are homozygous for bg :-

    not the best photos I'm afraid, but the colour rendition is pretty accurate

    Both fish below could be D/D - Sm/+ - pb/pb - bg/bg, but equally they may be D/+ or D/Gm and only het. for bg.




    I'm confident this next one is bg/bg but depending on mood, it's smokey pattern can darken considerably.



    I have however decided that for the moment I'm going to try to eliminate smokey from my Bulgarian Green breeding program, once I have a firm handle on how the gene expresses, I might reintroduce it, but at the moment it's one variable too many for me to cope with!

    Now on to batch #3
    I have also selected 14 fish from this batch to grow on as potential breeders, most of these are blushing. As I have limited tank space it helps to keep track of which fish are from which batch if I keep only blushers from one batch, only veiltails from another, etc. etc.

    As both parents are homozygous for pb that means these are all Paraibas, and unfortunately I'm finding these extremely difficult to call.

    Take this fish as an example


    At a cursory glance you might easily take this fish for a sunset paraiba (g/g - S/S - pb/pb). However, as it's father is D/Gm and it's mother is almost certainly D/Gm (and if not Gm/+) it can't be!
    Then, if you look very closely at the tips of the anal and dorsal fin you'll notice a tiny bit of black.

    Here are a couple of very similar siblings



    In these the faded black marks from the gold marble gene are more obvious as are the black tips to the fins.
    My guess is that all three of these fish are Gm/Gm - S/S - pb/pb - bg/bg but could the darker fins of the last two indicate D/Gm?

    At the other extreme
    Like father like son(?)


    I'm assuming this is a smokey pinoy ghost like dad, and only het. for bg if so he's D/Gm - S/+ - Sm/+ - pb/pb - +/bg
    Up to now I've not bred any D/Gm pinoys, is this typical colour for such a fish? Or is the single bg gene exerting an influence on expression?

    more phenotypes to follow....

    This one is probably my favourite





    Clearly a pinoy paraiba of some type but is it homozygous for bg? - only time will tell

    What about this one?


    Horrible lemon shaped body, the shadow of the smokey pattern is visible, but is it bg/bg?

    Just a couple more

    if both parents are D/Gm, Given the black tail band this can't be Gm/Gm and most have at least one Dark gene, but it doesn't look quite like any of Raiko's photos of blushing bg/bg that I recall seeing.



    similarly this one



    The smokey pattern is very apparent and it looks like a typical smokey paraiba, with no real indications of the presence of a dark gene, but if it is Gm/+ rather than D/Gm that presumably means the mother is Gm/+ not D/Gm in which case there should have been many more smokeys amongst it's siblings.

    Lots of questions rather than answers, but it does point me in the direction of my next pairing, I need to test cross the female!
