Ok, so I have a small blue tang I have had for about a month or a little longer. I’ve always noticed little spots on her face, but noticed tonight that there seems to be quite a few more than lately. She has a voracious appetite, (I love feeding time with her, she goes crazy!) in the tank I have also I have two clownfish and a court jester gift I got today. All the fish seem to be doing great! Also a shrimp, crab and hermit crabs and snails. Parameter seem good, although I have been barreling cyano bacteria lately. Any thoughts?
