Mystery bump?

[Salty&Onion]

I did couple photos of him and noticed a large bumb, I looked at him and there is no huge bump on his belly, only slightly bloated.
Does anyone know what is it??

I think that's just his pectoral fin.

No its not actually. I have looked at the photo.
I have circled his pectoral fin in yellow, and the bump is circled in white:

Yes, but if you look at the other photos you've taken of him, you can see that his pectoral fins are really big, bigger than a normal betta's. Also, if you look closely at this photo, you will see that the bump is actually see through.

That's hard I do sometimes have problems noticing stuff, the bump is not see through to me

If you look close, you will see the green of the plant through the bump.

I think that's just a reflection on the scales of the plants on the other side

Really weird as he originally does not have that bump on. Mystery still unexplained... 'X Files music plays'

But none of his other scales show any reflection...
