Does anyone know what this lump is ? Not sure if I should be worried. He seems to be behaving normally (eating and swimming as usual)

  1. Unfortunately it’s likely the start of a tumour. I had a beautiful turquoise betta earlier in the year & he had one of these, which very rapidly grew. Blue bettas are very prone as far as I’m aware. I let my guy live out his life until he began struggling. I had him for about 7 months.
