I also think the 'black diamond' is a type of leopoldi. Correct me if I'm wrong, but the wild type may tend to be found more often in a certian locality, but patterns in wild P leopoldi varies greatly and this 'BD' wild type interbreeds with P leopoldi that we would consider 'plainer'.

Perhaps 'Black diamond' would more accuratly refer to a type of leopoldi that in captivity certian individuals are trying to focus on and get to breed true- kind of like long hair in a cat but still all cats?

That is my assumption. They all come from the same freaking river. A BD and a leo HAVE to cross paths. They are the same fish, but my guess is that the BDs are nothing more then nice leos or perhaps locational variant of a leo.

As most of you have seen in the other thread, they are also called P. leo "Sao Felix" Well we all know Sao Felix is not a river. So where EXACTLY are these guys caught in the Xingu river system? Any one know? If we can prove that they are for the most part found totally seperate from Leos we can say they just might be something more then a nice leo. However, if they are found through out the Xingu right along regular leos, it gets harder to say that they are not just a nice leo.

I agree BD's are leopoldi and it's a matter of breeding certain ones with specific patterns so that they produce a certain trait. They keep doing this and get the perfect BD look.

From what I've heard, BD's come from a completely different part of the river than normal leo's, and because it's much further away from any major center, the costs involved with getting them were so much higher that it wasn't worth it before the ban when everyone just wanted 'black rays' and didn't really care too much as to which type it was. From pics I've seen of BD's beside normal leo's, the difference IMO is night and day - they are a darker black and whiter white. I personally don't think it's a trend, just people learning more about rays and wanting to know more about them.

BD's and regular leo's are found side by side in the xingu, I asked Patricia from Brazil at the symposium and she informed me they catch BD's and leo's in the same exact area of the river.

There you have it! FTW!

Looking at the threads lately I get the feeling that everybody want's their ray to be a Black Diamond. It doesn't seem to matter that all the rays that are posted are not. I have seen LeoXHenlei, LeoXBD, LeoXLeopearl or other hybrid of origin unknown. Just check the amount of threads lately on this topic. It is a real hype, soon people will be posting pics of scobinas asking if they are Black Diamonds or not.

A Black Diamond Leopoldi has the following appearance:

- leopoldi bodyshape, tail with 3-4 rows of spines and a short round paddle
- the coloring is black and white, usually the base is blacker than a normal leopoldi, the spots are whiter.
- far greater number of spots than a traditional leo and two exra rows of revolving spots, one on the disk edge and one just off the edge, there can be a few spots inbetween these two solid rows
- the belly is covered in revolving white blotches
- the base color of the eyes is white with sqiggly dark lines on them, many white spots surround the eyes
- the two rear fins are covered in white spots, males have white spots on their claspers
- the growth rate seems to be slower than that of normal leos also the maximum size is said to be smaller.

This pretty much sums it up, if anyone has anything to add feel free.

They say 'blub blub' when held above the water...

From what I have heard it is all a matter of gas. BD variants are found further up the river, the rapids are harder to get through, the gas required to get there is a lot more, and it is basically a lot more expensive to collect a BD. The economics of getting a ray for a few bucks (maybe) more bucks because of the way it appears didn't make sense.

Now that we have a quota and the value of these rays in the market is there, perhaps fishermen will now get the 2 stroke going and get the hell up the river!

Put two ugly people together and they make the most beautiful baby. Some things can't be explained about genetics. BD's just got all the good qualities, the other leos are just jealous.
