How many Costatus Armulatus have a pore behind dorsal fin?

Post by knifegill »

As the topic states. My raphael has always had a whitish depression behind his dorsal fin. It is on the median and just proximal of being exactly where the leading ray would connect when clamped. Is this a typical feature? Existing photos are usually taken from directly above, which occludes the area in question. I'm only wondering if this is a genetic defect/injury or something found in certain populations. I'll post a pic if I can get it.

Edit: Tried to grab him, he went nuts. I'll try an in-tank shot tomorrow. Also, the pore is dark now, the color of the rest of his body. Healed scar?
An opportunity to routinely impose a statement... I'll pass. ;)
