Hello! Today I have noticed that my betta has a tiny bump on his head (?) near his eyes. He is currently very active in his 16 gallon tank, and still eating regularly, but I am still worried about this bump. A quick google search says that it is a tumor, and I am not sure if it is. Apologies if the pics are not clear – he is quite active and always swimming to explore his tank and the plants so this is the best I could do.
