I would love to see photos of your BSP lines.

Very nice aqua.herp. Have you noticed the dark coloration comes and goes like with a Zebra angel? That's how mine are. One minute dark fins and black stripes and the next they look like an albino cousin.

Thanks cat, so far (only been about a week) he (guessing male) has stayed just as he appears in the pictures. I'm still a tad confused on the actual genotypes though. So they are both Bulgarian seal point(phenotype) which would be bg/bg, the one is ghost so that's s/+ but with the silver would it be D/+ or +/+ ?

You are not the only one who is confused!! I have found somewhat contradictory information and talked with others who each have their own opinions. I have seen D/+ bg/bg referred to as Bulgarian Seal Point and D/D bg/bg or D/Gm bg/bg referred to as a "true Bulgarian Seal Point". These terms themselves are leading to the confusion.
As far as I know (breeding may prove otherwise) any fish carrying at least 1 Dark gene with bg/bg may be referred to as a BSP. If there is no Dark gene present then the fish never displays dark finage and the body stripes will be very faint or possess no dark pigments.
One of my frustrations with breeding is that I have a small spawn where the parents were a Manacapuru cross (D/+ bg/bg) and a Blue cross (D/+ pb/pb bg/bg). YET, I have offspring that appear to be D/+ pb/pb bg/bg. This is not possible based on genetic info provided by Raiko. Further, the bodies appear to be olive yellow (or white) with a green cast in the reflection when catching light.
So, sad to say, with the presence of a Philippine Blue gene in fish that shouldn't carry this gene, we are going to have to isolate the bg gene and breed to prove no presence of pb before we can even begin the gene study.

Interesting. I guess when looking atleaat at my silver i just don't see any dark present? Looking at picks of lace angels D/+ I'm just not seeing the fin characteristics but I guess there is a lot of lacking info so breeding and isolating out the bg is what's needed

You are correct. In order for this organization to recognize and accept this as a new gene we need to breed and document. And the first step is to isolate the gene to ensure we can identify how it interacts on it's own as well as with other genes. Having fish where the breeder stated the parents were D/+ bg/bg only, and ending up with pb/pb offspring complicates our efforts.
The D/+ bg angels appear to have dark fins until they reach about quart size. Then the dark pigments begin to fade. It is assumed that this is the point where the bg kicks in. But at this point it remains a theory.
If/When you start breeding your bg angels, deep records. Document the parents, work out their genes, and take photos along the way. That is the only way we will gain an understanding of this new gene. And, if you choose to share those records with TAS then it would help with our efforts as well to document it.

Yes I plan to document extensively to help better understand this new gene and its characteristics. I'm acquiring 2 more greens early next week so I'll post pics for them too.
