HOLY COW she's beautiful! Reminds me of my wild caught girl when she was younger. Be prepared for the cirri to possibly be re-absorbed, but it might not happen since she's captive bred this way. Fingers crossed that she stays "hairy" for a long time.
My educated guess is that she's a she. Depending on size and age, it's possible that it's a subadult male....can you tell us how old they are or, barring that, how big they are? The tummy curvature suggests female, but the position of the anal fin would really help in that diagnosis...and I can't see it very well. The other thing that's making me second guess myself is the angle of the tummy....females usually "cut in" much more sharply than these pictures show. If there's ANY tissue that seems to connect the anal fin to the tail, it might be a juvie male.
Don't forget the awesome pic from the .org site:
