Yasha Hase Dorsal Fin

[tryptal]

Hi,

I got a Yasha Hase about a month ago and all is doing well. I had a question though that I can't seem to find an answer to online. She had a nice long cool looking dorsal fin appendage, but the other day I noticed that the top of it (Long strand like part) above the dorsal was gone. Probably nipped off by something. I was wondering if that would grow back?
This pic gives a good shot of what I mean. The long skinny strand part is completely gone. Not a big deal, just really added to the look of the fish and I was hoping it would grow back.
Thanks!

If it's a healthy fish, I think it's very likely it will grow back as long as the base of the fin is not damaged. That's a "best guess".
