Can anyone tell what this is? It looks kind of like a popped white head. Not sure how well that shows in the pictures. He seems fine. He's swimming like normal and eating. Should I separate him? What could I treat it with?
My Male Ram has developed a sort of pimple on the right side of his face near his mouth. He is still very colorful and seems completely normal... any ideas?
He is in a 29g with only him, a female GBR, and a SAE.
