Betta developed small lump on head?

  1. Miagates Initiate Member

    My betta developed a small single lump on his head. It's really small but big enough to notice. He's dark blue and the lump is light blue. He acts normal and eats normal. I have have him for a few months and this just appeared overnight. A cyst? Parasite? Thanks!

    Can you get a picture of the lump?

    One of my minnows has this too.
