Beta fish question

Question
I changed my beta's water yesterday.  I used spring water and even let it sit out for 24 hrs before changing the water.  My beta was swimming fine and now it seems since I changed the water, he's only swimming on top and can't swim to the bottom.  He tries to swim to the bottom but seems to float back to the top.  Does this have anything to do with the water change because before I changed it he was swimming fine.  Please help!!

Answer
Amy,                                                         Did you use a different water than usual? If so go back to the old water. I mean brand of water you bought.It could be a swimbladder infection , but that is awful quick for that to happen. Try feeding him a pea squeezed between your fingers let him eat the meat. Everyday for a few days. If this doesn't work try melafix it is all natural and mild. Treat him for 7 days. Then change the water. I hope this works for you . Good Luck,Tina
