Hi all, really hoping someone can chime in here, I have a leopard danio who has a cottony fluffy white patch on his back and part of his tail fin missing. I have pulled him out of the tank for a moment to see closer. The tank is a 66g planted with 2 gold gouramis, 2 opaline gouramis, 12 danios, 7 penguin tetras, 6 platys (+ fry), & 2 BN plecos. Water quality is good (0, 0, <5, ph 7.6 - api master test kit).
Here's some photos. What do I do!?
