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.
I disagree on the above..
1) If the pup have a slow growth rate or stunted than the spot are damn white even though it's only 5".. (you will know when you find that after eating a lot but still not growing fast)
2) 6" and above pups can still have yellow spots on the centre cos I have bred and grow more than 70pcs pure PDR pups till 8" before selling off.
From my experiences if the grow rate is fast than the yellow spots on the centre wouldn't disappear that fast. It's take about 3 to 4 months for PURE PDR to be completely white in the centre.
Just my 2 cents..
