As far as the symptoms that it says that they will have from brook:
-he is not scraping against anything
-he has been breathing normal, does not look like he is strugling for air
-I do not see any signs of mucus, the white seems more like a mark or scar if you will.
-He did not eat last night when I feed brine shrimp, today at lunch I went home and fed him some spec. pellets and he was eating those.
-He is not hanging out by the top of the water, he is swimming more now in my hospital tank then he was in my DT since he does not have one of his RBTA to hang out in.
When he was in my DT he should hang out in my RBTA all day long, a lot of the time he would just sit on it and not swim. My other clown would then try and display its domance on this one and pick on it unit this stick one would lay on its side and and just lay there, the other would then let up and leave it alone.
Does this still sound like Brook? If so I am going to start to treat for it as so as I get home.
