the only thing I can think of is I did use a bit of metro in frozen bloodworms ,( I had my baby texan x escondido with a bit of string poo ) just in case but his mate is fine so I just dont know, hes a hell of a fish, loves to get tough with you when you shake your head at him ,but its been two days and no change ,doesnt seem to be in pain ,no thrashing or any thing ,just stuck there
