Hi I have a green severum in a 55 gallon tank with a bristlenose plec 3 x giant danios and a firemouth, and 1 tiny cherry barb which is from my old tank all small fish which will be moved to a bigger tank as they grow. I noticed the severum has a mark on just above his fin is this a mark from fighting or a illness?? Please help?!
