Ok so I added some aquarium salt to the tank and he seemed to go back to normal. I did a 40% water change today and he's back to acting super strange, he is much worse with these actions then in the video. What do u guys think??? I first noticed it after the the last water change note I just started adding water directly to the tank and treating the hole tank with prime all the other fish seem ok but he seems stressed. http://s1277.photobucket.com/user/j...140803_200839_zps0dc0defa.mp4.html?sort=3&o=0
