Bubble Corals normally require moderate lighting, though some specimens accept bright lighting. Mine love very bright light, right under my metal halide light. . Water movement should be low to moderate, and any powerheads should not be directed toward this coral. It will rip the bubbles.I noticed that for the past couple days, my bubble coral hasn't been inflated much. The shrimp won't climb on it anymore, so it can't be that. please help me.
