Have been asked for a pic of bump and hopefully it will come thru. Anyonre seen anything like this?

 

[THE V]

I've actually seen something like that on the caudal fin of my koi a few years ago. It was a small bacterial infection that grew and then popped. I fed them some antibiotics (ampicillin) and the fish healed up just fine and none of the other fish had any symptoms.

It might also be a cyst or small tumor. Strange stuff.
