I changed my beta's tank this afternoon. About an hour later I noticed he wasn't swimming so much as letting himself be carried along the current. This is when I remembered (like an idiot) I forgot to put in the water safe agent. I ran to the pet store and put the water softner in, but slowly I started to notice his color change from a vibrant blue/green to a pale bleached color and now it's settled on a darker almost navy blue color around the edges of his fins and his eyes turned cloudy. I warmed up his water, thinking it may have been too cold and he's started moving around a bit more now and his eyes are back to normal. Still, I can't help but be concerned. Did I bleach him, burn him, or freeze him? Will he be ok, and is there anything I can do to make sure he pulls through? I'm a bit frantic at the moment...
