This has been driving me nuts for quite a while now...for the longest time I just assumed he was the same as my golden laced seabright until he became older and his tail dropped down like that..so i started comparing him with the seabright and noticed his hackles are totally different and the darker spot on his back has a greenish tint to it! Idk if you can see the green that well i first noticed from sun hitting it. Is he a sex link?! Really hope someone can help it’s driving me nuts!!!
