333's are also known as gold/ yellow king tiger vs the 66 who are king tigers super golden 333's are a Very high grade the whiter ones are a lower grade. My 66's are pristine white with super finelines some people have thought they were juvinile 260's ( could have made a killing if I was super dodgy )

Picking juvinile 333 and 66 is a massive pita the color of both species ranges from white to yellow generally the 66 have longer tails bs body length and as I said are a black fish with fine white/yellowish lines where as the 333 is a white to gold fish with black lines but again it's all perspective.

Just hope the breeder knows what they have
