Default Identification of Black Diamond P13

Hi all, given my limited experience on Black diamond P13... Will try to share with fellow brothers/sisters on how to identiify PDR/Grading of Black Diamonds

Here are the following on how i grade these rays.....

1. Spots should be white even when young pups....

It is always encouraged to buy rays when they are conditioned. Conditioned means stable when stable down the pups will enhance its base color and spots. For PDR/Black Diamond, the spots MUST be white in color. 6 inches and above pups are deemed white spotted. Should not be any yellowish spot throught the whole body.

2. Spots rows from centre to skirt....

PDR have at most 4 rows of spots being identified as high grade of PDR. Some have 5th row spots but minimal can be see. 321 pdr are termed 3 rows of spots only. Below pic illustrated on how to see how many rows of spots from a ray. For a black diamond, 5th row and 6th row can be seen visibily well. 6th row of spots for BD will be one grade higher. But Big spotted BD most of the time has full 5 rows spots also term high grade bd like this pic.

3. Skirt spots

For BD, skirt spots should be continuous with minimum break off point. Some BD have 2 rows of skirt spots thus being termed 6th row. PDR do not have skirt spots at all.

4. Spots in Eye

For BD, Most of the BD have spots in eyes..... the more spot the better to enhance the blue lens effect thus many brothers here termed blue eyes... But i do notice some BD eye dont have that much spot in the eye. So termed as another grading on BD. As for PDR, some have and some dont have as well.

5. Spots around eye....

For BD, Spots surounding the eyes should be as much as possible..... so when they grow bigger .... the whole eye portion is white with spots.. PDR do have such features as well.

6. Thorns on the tail....

According to Taiwan identification from what i learn.... 3 rows of thorns should be situated on the tails.....

7. Flag shaped and short tail....

When BD/PDR are young, their tails should be relatively shorter than the body. One look give u an impression of short tail feeling kinda identification. No exact lenght is being documented. PDR/BD alll have FLAG tail.....

8. Under belly spotting ....

Some BD have underbelly spotting.... the more the merrier... termed graded as another higher grade catergory. Some BD dont have. PDR most of them dont have .... only high grade PDR will have such spots prominent when they grow bigger...

9. BD grading ..

BD have Thousand Island BD, Big spotted BD, Eclispe BD ...... if any BD comprising all or any 2 of these are of course a much higher grade compared to normal BD ...... so if u have possession of a bd that has all 3 mentioned.... that is a priceless piece ..... like the pic attached ..... the piece had 2 of the above mentioned category. PDR is being grade as such too but spot sure definitely be lesser

Enjoy Ray keeping bros/sis...

yes WC rays are being caught in the wild ....these rays never get to enjoy good quality filtration water but only river water explaining why the spot are yellowish... when being groomed in pond and tanks.... the spots will turn white eventually.
