I went to Petsmart with my hubby today (he needed crickets for his frog) and saw this guy while perusing the bettas. I don't have any extra room since I have a few fish from Thailand arriving in the next few days... but it was certainly interesting to see! I rarely see anything but blue, green, red, and multicolor bettas at the local Petsmart/Petco. Even if they have different tail types, the colors are pretty normal. It was even crazier for me to see a VT with mustard gas coloring...
Sorry for the pic quality!
