Most of my fry have gotten up to 2cm to 3cm. Most of the showing blue jewels on the gill plates. Are these mostly males? Some are starting to show some jeweling on their sides. A couple are starting to show a little jeweling on the anal fin. I'm thinking those are males. Some seem to have a over all yellowing appearance. None are showing the sharp tips on the dorsal or anal fins yet. Is there any subtle indications to start sexing at this stage. They are roughly 14 weeks.
