My friend and i bought clownfish when we set up our tanks. All from the same batch. After 1.5years his are 1-1.5in bigger than mine. I feel like mine have barely grown. He feeds just pellets while i feed a variety of pellets, frozen, and nori. I have two clowns that have established sexes. They are 1.5-2in big. Female is .5in bigger. I just want them to grow bigger, and pair off.
