Your boy is a gorgeous platinum or white.
Do you have a recent photo of your other boy? A Black Orchid is defined as a black Betta with streaks of steel blue in the fins. The body is black. Note how the steel blue is patterned in the example. Very distinct. It is my understanding Black Orchids can have white on their ventral tips but not on their body.
If your dog thinks you are the greatest do not seek a second opinion
