I have 2 firemouths and a severum in my 55 gallon and I'm just trying to figure out if one of my firemouths is attacking the other one and the severum. I've noticed the tail fins on 1 of my firemouths and my severum are split in half kind of. The other firemouth has a full tail fin and is perfect. Could it be finrot? My tank is finally been over ICH now I have to solve this problem. What do you think?
