Nick,I'm less confident now that the second baby hatched haha. You can see the second baby has the black rings around her dots which looks just like an adult female where the first does not. Maybe Jurgen can help?
My clutch of these didn't make it, but going from my past Campani, I'm fairly confident baby #1 is male and #2 is definitely female. Congrats on your success of getting viable eggs to hatch!
