I picked up this purple tang cheap. I'm pretty sure it has HHLE. I've been feeding my homemade fish food soaked in Selcon ,spirulina brine shrimp,nori,Sprungs sea veggies and fresh clams. I have some LRS foods coming in soon to feed too. Other than diet what is reccomend to treat it? It doesn't seem stressed at all and eats like a pig. My water quality is good with nitrates around 5 ppm and other parameters also in spec.
