mmm I've had a look at the description of a black orchid "black Orchid
A Black Orchid
betta will ideally have a black base together with a black banding of all 3 fins. The blue/green or steel must be present in the tail as shown to the left (bred by DP Fishways) and also in the anal and dorsal fins. A very slight blue scaling is also acceptable on the body."
which is close but I think he probably had a bit too much colour in his body from the photos.. he was described as a blue so I can't wait to see him in person because he looks much more greeny
