Grow back? Fin rot. How long?

[curtcherry]

Christmas wrasse had fin rot. Have treated with kanaplex and on day 5. Third dose went in this morning. How long does it take a pectoral fin to grow back? Weeks, months?

Usually takes a week or so to grow back, depending on the severity of the injury.

Yes, soft rayed fins regrow extremely fast and usually without any trace of the previous damage.

Hard rayed fins may take months and not always regrow completely.

Fins may regrow incomplete if the fin root/base was damaged.
