I've noticed that many of the bg, and especially the seal points, acquire the swept back, hooked?, dorsal.....at what stage does this develop ?...
I have seen a certain amount of these, but haven't done a specific count, however the photos in the previous post hopefully show that the majority of these fish haven't developed the trait. Also, many of the fish that did develop it weren't Bulgarian Greens, so I'm inclined to suspect that it's not a trait specifically linked to or caused by the gene.
