So i just got two clown fish about 3 days ago. i have two different types of food for them that the lfs said i should give them. He said it was what they give to them. One of them is sinking pellets calle spectrum Thera, and the other is a flake food made by ocean nutrition that has brine shrimp in it and veggies. My problem is that they don't appear to eat either of the two. Is it normal for them not to eat in the first few days? They seem interested in the food though. They swim up to it bite it, and spit it out. Is there something wrong?
