Hello there. Over the past five days I've noticed a sudden decline in my female swordtail, Auraques's behavior. She hasn't eaten a flake in the past 4 days or more. She is now always irresponsive.
Recently there has been an outbreak of mouthrot in the tank and almost all tthe fish were infected with it. It came from a from a Lemon Tetra from my LPS that I failed to quarintine. When I noticed it on the Tetra I isolated it in my hospital tank. It died 10 days later, but I thought the mouthrot died with it. I watched my fish very carefully over the period of the next few weeks. Then, I let my guard down. I found my female swordtail had an extreme case of mouthrot, and the other fish had bad mouthrot. I treated the tank for the next week or so, along with multiple large water changes. I thought it had been taken care of but it came back a week later. I remedicated the tank and maybe I got rid of it this time. But my female swordtail is still sick!
Here are the symtoms; Silver gills, misformed gill, always resting on the gravel, not eating, not social interation with other fish or even me.
I have a hospital tank I can isolate the fish in if I need to. I am very concerned about this fish and the rest of the tank. Any advice would be greatly appreatiated.
