My saltwater aquarium has just been set up for a week now. I have 2 ocellaris clownfish, 1 orchid dottyback and 1 blue saphire damselfish. The small clownfish hasnt been eating for a couple of days, and is swimming weird. He's acting lethargic, fats breathing. Tank is cycled, water parameters ideal, water temp 78F and salinity is 1.025. He is the only one that's acting weird. He ate before and now stopped eating.
