My Betta is at the bottom of the tank and it looks like he is breathing heavily. This is my fist partial water change with him and I don't know if he is just mad that he got taken out of his tank and stuff or if something is wrong. It happen right when I put him back in the water.
I live in Hawaii so the tap water here is okay for Betta fish to swim in but I conditioned it anyways but I'm not sure if I mixed it well enough. I didn't add a full dose, which is a cap-full for a .5gal tank which is what I have. I put about 1/4 of a cap in. Help?
