So I had recently got these 2 flowerhorns and I believe they’re Gb Fader FH but I am not sure. It is the spawn of a Male GB Fader and a Female Red Blood Parrot. I’m not sure how old they are but I think the bigger one is 9 months and the smaller one is 6 months but I’m not sure. If you can help me figure out the gender that would be nice. I also would like to know how to grow their nuchal humps (kok) I placed a mirror everyday for a few hours and I feed him hikari Cichlid Gold just until my okiko package comes in.
