A couple days ago my GT looked like it had caught it mouth as one side was hanging open.
However today its mouth looks like it is covered in fungus and also its side fin.
I have attached some pics however apologies for poor quality as it wont stay still.
Any ideas what it is and if its a risk to my other fish and rays? How can it be treated?
Tank is 4x2.5x2. Nitrate below 20. Nothing else changed.
Its still is eating fine and other tank mates fine
Thanks in advance all
