Bump/cyst on head

[darksea13]

Two days ago I got up and went to feed my betta and noticed a bubble near his left eye. There could also be a little bit of whiteness on his head, but I thought it was just his coloration. His appetite and behavior is normal, he even made a nest not too long ago so I assume he is happy. I don't want to make any guesses as to what this could be and incorrectly treat him. Sorry for the blurriness, he wouldn't stay still.

Is it fuzzy at all?

[darksea13]

No. It looks smooth and almost translucent. It doesn't seem to be affecting his eye either. The white patch on the left side bothers me too, but it has been there as long as I can recall. I put some dissolved Epsom salt in this evening and will see how that changes things, if at all.

Can you get a clearer picture? Two things come to mind... Either a tumor or cyst like growth, or an injury healing... But unlikely for the injury, as usually it is "fuzzy" which can be slime coat or an infection.

This was the best I could do.

Hmm, definitely looks like a cyst, or something similar to a "water pocket". Make sure that if it were to puncture or explode, that you have the water in top condition to avoid infections. I would try the epsom salt, see if it goes down. If it is a cyst (usually a solid matter that is from the build up of bodily fluids, probably won't break down) or a tumor.
