Hi everyone,

I am writing because I am concerned about my cardinal tetra. It seems to me like he is sick but I do not know how to diagnose the problem. I think the problem is fin rot but I am not sure. I am attaching some pictures with the hope that anyone can help me determine the problem and recommend a treatment.

Thank you for your help,

Yenny

It looks like fungus. Do some water changes and add some melafix.

No problem! Do you have any other cardinals in the tank? Do they have any symptoms?

I don't think he is stressed out. He is ok with my other harlequin rasbora fish. When I brought other cardinals to the tank they were bullying him, so I took them out.

Really, cuz they will chase each other every here and there(they have a pecking order, almost all fish do). I know,I got a school of 15.
