My green mandarin has developed a white spot (circled in red) he is eating fine and acting 100% normal, im worried however its a disease of some sort? I know they are naturally resilient due to their coating but the spot has me worried! All other fish are ok in the tank and all get along fine. Only change is that my young pair of clownfish have started fighting the past few days I assume one is switching to Female. Could this be a wound ? I know the sand sticks to their coating which this doesn't look like to me..
Many thanks in advance !
