Very nice body and head pattern on those brooksi!
I heard that the more red their head is, the more likely they will retain their red color as an adult. So in selecting a flame brooksi, pick one that has the darkest and deepest red color on their head.
I have a red hypo brooksi (not a true flame), and his color is fading as he gets older. He's a light orange now and could possibly even turn yellow, which is fine with me. I love him regardless of his color!
