I've had this tank for 2 years along with these clowns, nothing has been added recently but I've noticed these marks on the side of the female clown. both of the clowns are in a qt with prazi and are being fed metroplex/focus coated food. What should I do? is this merely an irritation and I'm overreacting? help!
