I have a stingray, yellow tang, sailfin, blue hippo tang, 2 clowns, 2 yellow clown goby's, coral beauty, copperband and raccoon butterfly, etc., I am getting my new MH/T5 lights Tuesday, and I definitely plan on adding some corals...the 2 yellow clown gobies seem to love the tall plant...LOL...I eventually want to add more rock in the center, bugt I need to keep open space for the ray.
