Just put him yesterday from LFS who has had them for awhile. I got the last two. One was a little tattered on the dorsal fin but acting fine. Today, he's just kinda floatin around the tank with the current. No visible signs of anything. Every once in awhile goes nose down tail up and actually flips over, then catches himself.....any ideas? I am gonna have to ice water him in a minute. trying to upload a vid taking too long. Should I drop in ice water....now hes completely upside down and struggling to breathe.
