Actually, I wouldn't consider this fish a true spade tail, while the tail resembles a spade in shape, that is a very common expression of the veil tail trait in females. True spade tails as well as true rountails are very rare these days because they are recessive to veil tail, and they just aren't popular like they were before the halfmoons and deltas came to dominate betta breeding culture. No one that I know of is working with round tails or spade tails at all. Occasionally, you will see a HMPK with a spade shape, but these aren't really what I consider true spade tails either.
