Mixed Reef Aquascape Ideas

A mixed reef tank combines soft corals, LPS (large polyp stony), and SPS (small polyp stony) corals in one display. Your aquascape—the way you arrange rock and coral—matters because it affects water flow, lighting, coral growth, and how easy the tank is to maintain. A good layout keeps corals healthy, reduces algae problems, and creates a natural, eye-catching reef.

Key Points

• Plan zones for different corals. SPS corals prefer strong light and high flow, so place them high up on rock “peaks.” LPS usually like moderate light and gentler flow, ideal for mid-level shelves. Soft corals can handle lower light and variable flow, making them perfect for lower rocks or the sandbed.
• Use open, stable structures. Aim for arches, islands, and shelves rather than a solid “rock wall.” This improves circulation, reduces dead spots where detritus collects, and gives fish places to swim through and hide. Always secure rocks firmly using epoxy, glue, or interlocking pieces to prevent collapses.
• Leave space for coral growth. Corals will expand and spread, so leave gaps between frags and rock faces. Visual “negative space” (bare sand or open water) also makes the reef look more natural and less cluttered.
• Common mistake to avoid: Overpacking the tank with rock and corals too quickly. This restricts flow, makes cleaning difficult, and can cause aggression as corals sting or shade each other. Start simple, then add more as you learn how your corals grow.

Quick Summary

For a successful mixed reef aquascape, think in zones (SPS high, LPS mid, softies low), keep the rockwork open and stable, and leave room for future growth. A thoughtfully planned layout makes your tank easier to care for and lets every coral thrive.
