I have a 150g tank with 11 fancy goldfish of varying sizes, dojo loaches and some kubotai loaches. I had some plecos in the tank but one of them was an eye eater and has been removed. Now that I'm sure the eye eater has been removed I started seeing sores just behind the head along the back of 2 of my goldfish. This started 2 days ago and I had to get some things together for a quarantine tank but it went from "what is that" to "oh my God" way too quickly and put into a 29g tank with aquarium salt and fin & body cure as soon as I got home.
Is this ulcers, just to confirm because I know that's very contagious and want to try and treat the whole tank if so, but quarantine the 2 that have it worst so they can recover in peace. Please let me know, I love these guys so much and Muffin, the Lavender oranda is my special little girl 8C
No one else is showing any symptoms currently but I am going to be watching them like a hawk.
Also in the pictures it looks like white spot, but those are just bubbles, just wanted to clarify.
