I bought a clownfish 3 days ago. The clownfish is swimming and breathing normally and has no visible sighs of disease. He is very active too. When i feed him though he barly eats any of the mysis shrimp. My tank is about 2 month old 10 gallon with 8 pounds of live rock. About a week ago I started noticing copepods crawling around on the rocks and glass. During the day I notice my clownfish eating copepods. Is it possible that hes not hungry because hes been eating the copepods or is it something else? Also my water has 0 at all toxic levels but the ph is a bit low.
