Thanks everyone! As suspected then, Ryu is a juvie PK (Unless as he ages his fins become something else?) I'm not sure why but that makes me glad, I guess it's because was prepared for a male.
Interesting fact about my LFS,where I got him. They have well over a THOUSAND Bettas there, and 95% are healthy and in clear, clean water. Everyone gives them the VT's and CT's they breed and they get probably 50-100 thailand fish every visit (the fancy ones are the thailand ones) "That place just AMAZES me (they have a room just for Bettas and keep all the giants and HM's possible in 1 gallon tanks) Next time I visit I'll post some pics!
