Uh.... I don't know how to just get the fish's pix.
Is this a crooked spine?

Hello all.
I am in the market for a nice double tail. I can't believe how hard it is to find an American bred one. Anyway, I've been searching aquabid and this particular fish is not American bred but it caught my eye, but something is bothering me. Is this what a DT is supposed to look like or is does it have a crooked spine? I guess I just don't really know what to look for and would like some advise.
Is this correct?

Found this while surfing the world wide web... Hope it helps
Here are those undesirable traits of DT that I select to eliminate them from the line so that these traits will not pass o*n to the next generation if they are used in breeding.
The following will show a series of those undesirable traits of DT.
1. Uneven Lobe
Usually the upper lobe is smaller than the lower lobe.

2. Y-Split DT
The split is of Y-shaped and it is somehow ugly and will not have those desirable overlapping lobes.

3. Crooked Spine
This is rather common in DT as well as ST when DT gene is present. A slight (I said SLIGHT) curved spine is acceptable for DT as it’s a common trait of DT, but any curved or crooked spine for ST is definitely unacceptable. Too much crooked spine for DT is highly undesirable for breeding as it will pass o*n to the next generation.

4. Deformed Body
This is also quite common when the DT gene is present causing the body to deformed or sometimes shortened. Never use these for breeding. If you used such deformed or shortened body fish for breeding, the deformed gene will pass o*n to the next generation and you will find that most of the body will become shorter and shorter.

5. Fused Lobes
These is an extreme case of incomplete split of the DT. Both the tails are fused together. o*nly choose those with total split tails.
