Well the verdict is *IN*. I cupped Piper and had a good look and she definitely has an ovipositor. It was difficult to see because her underside is a light sandy colour and those big ol' fins kept hiding it. There is a lil tube there though. You'd figure it'd be bigger on her since everything else is.
But if she has an ovipositor then why does she flare like a boy? Yeesh!
Yup, egg spot doesn't always mean a girl....its very common to see ovipositors on young males, which is why its not the most reliable way to tell genders. Hayate has an 'ovipositor', and I've had another young male that's had one as well.
I still say Piper is a young male ;) But I can't wait to see how he develops, be sure to post pics! :)
