Why is my betta fish fat on one side?

my beta fish belly is fat on one side whats wrong?

well das not a question

umm its not in water is must be wet but its dead...hahah get some water or a new fish!

On 1 side? I don't know. Maybe its pregnant?

Its pregnant. Congradulations!

Its probably pregnant!

I'm having the same issue... well my betta is fat on both sides. She now looks like a marble with a tail. Thought she might've come home from the pet store preggers but they said bettas lay eggs so there's no way she could be preggers.

Take the fish to the pet store and they'll test the water for parasites.
