Im new to the hobby so bare with me, i currently have two clowns they were purchased together since November 18 and all of a sudden they are acting weird, lets start by saying the bigger clown is going after the little one, and today is the first day its happening, 2 they are constantly by one rock, the little one looks like its scratching its self against the rock from a distance but when i observe closely its just close to it and the bigger one is swimming around the little one. There is no signs of ich or Brooklyn, Please help so i can sleep at night lol Water parameters are good and its just them and 2 snails, this is a 40 gallon breeder reef tank in the making
