My Tetra has developed a lump on its head. I have never seen anything like this before and I am not sure how to treat it. Tetra is about 4 years old and has always been in good health. 120l tank shared with a couple of adult and a dozen juvenile Guppies. Juveniles were born a couple of months ago. There are also a couple of Plecos. I carry out water changes on a regular basis and always add a small dose of Melafix at those times. I have checked all water parameters and they are good. This issue developed about a month ago, at least the first time I noticed it and doesn't appear to have gotten any larger since. So far I tried treating with "King British disease clear" for a couple of weeks, then made a large water change. Started a treatment with "King British fin rot and fungus control" last week, but so far no change. The Tetra itself appears to be fine, other than this. Eating well and swimming ok. I have put it into a small internal floating tank just in case the fish dies and the others start feeding on it, I don't have a quarantine tank setup.
All of the other fish in the tank appear to be fine, feeding and swimming well.
Can anyone help me identify this disease and recommend a possible treatment?
Many thanks in advance.
