Fin Regeneration in Discus
By Peter Lee
2002

Tattered appearance to dorsal, anal, and caudal fins is due to "fin rot" which developed

immediately after being received in shipping May 2001 when this fish was less than 2" standard length.

Discus was treated for degenerating fins at that time - lesions healed and fish regained health quickly and grew to ~5.5" total length but it never lost the tattered appearance to its fins.
