So now I'm concerned but think I'm on the right track.. @vetteguy53081 @MnFish1 .. the reason I bought rally is because I'm suspecting a gram negative infection in my water. I just watched my sunrise dottyback literally take his last breath. I did a fw dip no sign of flukes but there's something like bacterial on the dottyback like it's rotting on both rib cages both sides in the exact same spot. I noticed my tomini tang had a black spot a few days ago on his tail and today there's a hole where the spot was...does this sound like a gram negative bacteria? I will try to post pics below of dottyback please tell me if you can see them. Or what other methods I can use to post them please.
