Well we've already worked out how to sex this species from above once mature, but most often in a shop you'll see their undersides stuck on the glass. So what's the differences from below?
Female is left, Male is right.

Female has very visible vent. Big difference in leading edge profile of Pectoral fins. Male has "shoulders" while female has more gentle curve.
The female pic is from today, the male from not long after I got them. I think his "shoulders" are more pronounced now.
