This fish has me heartbroken right now!!! It won the judges award at the pioneer valley show. Art L. Said it had a real chance to become a Jumbo..I was very proud of my Ogata female ginrin kohaku.
On the ride home...they were all well bagged with oxygen, and in plastic crates. No tops on the crates...only a bag with rubber bands.
Well..when I got them home, this one had an injury. You can see where the dorsal fin had cracked. She must have been jumping extra hard. The crack is pretty distal...not near the base. The skin that connects the spines was intact. All I did was give an injection of nuflor...and she is back in the pond (after quarantine.)
Is there anything else I should do to treat this? Any chance of this growing out and resolving well?

Thanks for any help or advice.
