Yes, it very well could be.
Lol, I have a fish who's frightened of cameras too!
But yeah, if he looks like he swallowed a little ball, he's bloated.
That's why he's always floating at the top.
It's recommended to feed your fish 4 pellets a day (2 in the morn and 2 in the eve)
and to fast him once a week (not feed at all for a whole day).
If he can't poop, feed him some daphina.
