Hello just notice these marks on my yellow tang. Can this be from him and my sailfin battling over top dog? I know they get into it once and awhile IMG_2211.jpg
 
Red blotches are a sign of a bacterial infection. This might stem from aggression, but I’d be pulling it to treat in a hospital tank along with looking at my tank parameters.
 
I’ve seen those yellow stripes normally on yellow tangs, so I think it’s ok, but I’m not an expert
 
So if i can’t catch the yellow tangs can i treat with pimafix and melafix on display since it’s all natural?
 
No. Never treat in the display.
Most medications contain copper, which will leach into the rock.
I would use multiple nets and patience, even though the nets could get tangled in a tangs spines.
With that said, there are multiple tangs now?
 
No sorry only one yellow tang. Okay how long does it typical take for the infection to clean up
