So, my little Sakana again... he's always had a little spot on his back that is darker than the rest of him... he is somewhere around 2 years old now. He's still acting normal, but I noticed a tumor on him today. (I'm sure it didn't pop up overnight... I just noticed when the shadow hit it.) It's about halfway down his back... just to the left of his spine.
Is this something that could be fatal?
If not, then what else could it be?
Could it be contagious? He's in a divided 10 gallon with 2 other bettas, and I would hate for something to happen to them...
