I have a Walmart Betta, Edgar who has had something wrong with him. He was completely grey and nasty looking about a week ago after adding BowlBuddies' Water treatment tablets to his tank for the first time.. It got him sick to where he was looking gross! He seems to have recovered from that and has a little bit of his color back however his color is still faded. I have quit using the water treatment stuff that I bought and he seems to be doing fine. He is blowing tons of bubbles and seems to be happy as can be. Although the color in him from the neck to his head is still a little grey as in the picture I've uploaded to this post.. He used to look like my avatar.. I have no clue whats going on or how to get him better... His activity is happy and he's eating like crazy but his color is just a tad off.
Thanks a lot for the help guys!! :)
