Illness & Symptoms
How long have you had this fish? Since January 2022
How long ago did you first notice these symptoms? Yesterday (8/1)
In a few words, can you explain the symptoms? One of my harlequin rasboras seems to have lost a patch of scales on one side of its flank, and the skin seems darkened in a large patch that extends across the belly to the other side. Tail also is a little torn.
Have you started any treatment for the illness? Not yet, but I moved it to a QT tank
Was your fish physically ill or injured upon purchase? No
How has its behavior and appearance changed, if at all? Yes, see above.
Explain your emergency situation in detail.
(Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
We were on vacation all of last week and just returned this past weekend. Yesterday (Tuesday, 8/1) while feeding our fish, I noticed what seemed to be a large patch of orange-y scales floating in the water. After examining our rasbora school, I noticed that one of them seemed to be missing a large patch scales on its flank. Its flank is dark in a large patch and almost seems like a sore; this also extends across the belly to the bottom of the other flank. Its tail is torn and it is losing color. Our nitrates were rather high so I did a water change in the main tank and moved the sick fish to a quarantine tank last night. I have not treated with any medication at this point. The other fish in the school seem fine. I am not sure how long it has been like this since we just returned from vacation, but I did not notice any issues when we did our pre-vacation water change on 7/22.
Any ideas what could be happening? I'm worried about this little guy.
