Ok so i got nine out of this guys spawn on another web site (all my metallic SDxHM babies)
I got them in feb and they were 3 months old.
i just showed him these pics:
he said and I QUOTE:
"The ray extensions that look a bit like crowntail are unusual. None of the females I kept from this spawn are exhibiting this. Is it possible that it could be something less desirable, like fin rot?"
I pointed out that the rays split from quite low in the tails.
I dont think its fin rot. I'm certain its not, they are all in beautiful clean water. all 7 ladies are displaying this tail, three are in a separate tank and still their tails look like this.
