bioload wise its fine, but this is how i see it a tank needs to be very diverse, i have a 135 also and this is what i plan to do and am doing, there needs to be a few big fish and many small fish like the ocean it will give your tank good diversity, a good look, and a close simulation to the ocean. say you have 15 chromis, the clown fish, and like 6 or so other small brightly colored fish, then 3 or 4 big fish, it would look so cool to have big fish going through the schooling chromis.
