Hi Everyone, I have a small shoal of 5 silver dollars in my 135 gallon tank and I've noticed several markings on their tail and body (both are diffent). On one of my Silver Dollars I've noticed a black mark on one of their bodies, I've noticed the FireMouth chasing them lately but no harm is done. The black mark is only on one of the Silver Dollars. Another mark is a white mark which is one 3 of my Silver Dollars. Some of the marks are on the tip of the fins and are also displayed as white dots on the fins. I don't believe it is ich, is it just nipping or a bacterial infection? Pictures are attached and thanks in Advance. @CindiL @NavigatorBlack @chromedome52 @Anders247 @TexasDomer Thanks Guys!
