It started as a small singular white spot on the side of her tail. Became a little bit bigger, but now, after Christmas and me returning home, half of her tail flesh is gone. What is this?

  1. I’m not 100% sure it looks like general fin rot to me I don’t see any worms coming out so that scratches out nematodes for me when was the last time you did a water change? How big is your tank and what other fish are in the tank? Do they also have signs of fin rot of just this one fish?

    What other fish are in the tank? That dude looks like someone took a bite out of him. Fin rot breaks down from the fins towards the tissue, this is a chunk missing that didn’t even have a fin to begin with. I think I even see the spine in the middle.

    Is the fish swimming ok? Might need a antibiotics but I don’t know how well a fish bounces back from a deep wound like that. I have also had terrible luck with CPDs though.
