Hi, i have a 65g reef tank, and I was wondering if i can have a leaf fish without it eating any of my fish. They grow 4 inches long, so i dont think they will be able to consume any of my fish. I have 2 clowns, tomini tang, diamond goby, YWG, and 2 PJ cardinals. In the future i want a mandarin dragonet. Would these be in danger?
