my fish is fat

Question
Hi, Ive had my male betta fish for a while now and ive noticed that his little tummy is the size of a small marble. It looks like hes bloated. HE lives in a bowl and hes all by himself. we feed him about 2wice a day. and we just fill it up with tap water. Whats wrong with him?

Answer
Amanda,

Do you use the proper water conditioner before putting him in the tap water? If not - this could be early signs of a swim bladder problem due to insane metal/ammonia content. If not, it could be constipation or an internal parasite.

Try the water conditioner first and if that doesn't work, send another message my way.
