I have a pec pair and two damsels but the clowns are new in my tank and small. The damsels eat good but my clowns seem like they don't care for the flakes and they eat scraps. My red banded shrimp eat more then them. Should I try different food the LFS said they fed them random kinds of food. They only been in my tank 4 days I don't want them to starve. They get along fine wit the damsels they swim together everybody is happy. What should I do??
