Coral Reef Awareness Week is celebrated from July 21 to July 27 this year. At the brand-new Coral Reef Up-Close habitat, now open inside the Tropical Reef Aquarium at Point Defiance Zoo & Aquarium, guests can explore the vibrant world of coral reefs.

Bicolor and redfin anthias

These colorful fish bring motion to the reef, swimming in shimmering schools above the corals. They are small, active fish and rely on the coral reef for shelter and protection from predators. In turn, their constant movement helps stir up the water, circulating nutrients and oxygen that coral and other animals need to thrive.

Razorfish

Razorfish are sleek, oddly shaped fish that swim head-down among the corals, using their unique posture to blend in with sea fans and soft coral. They depend on the reef for camouflage and safety. Their presence helps balance the reef food web, as they feed on tiny invertebrates and plankton that might otherwise overwhelm the ecosystem.

Copperband butterflyfish

With its long, narrow snout and striking yellow-and-white stripes, the copperband butterflyfish is easy to spot. This fish uses its beak-like mouth to reach into crevices and nibble on coral pests like tube worms and small anemones. Feeding on these potential threats helps keep the coral healthy and free from overgrowth.

Lawnmower blenny

This hardworking little fish earns its name by munching on algae that can quickly overrun coral surfaces. It helps prevent algae from smothering coral colonies, allowing them space and sunlight to grow. It thrives in the shelter and hiding spots of the reef’s complex structure.

Hermit crabs

Essential to the reef’s cleanup crew, hermit crabs scavenge leftover food and organic debris, keeping the environment tidy. These crabs often wear discarded snail shells, helping recycle reef resources. Their cleanup efforts reduce waste buildup, helping maintain the reef’s delicate balance.

Banded coral shrimp

With its candy-cane coloring and long white antennae, the banded coral shrimp is a favorite among divers and aquarists. It’s also a diligent cleaner, setting up “cleaning stations” where fish come to have parasites and dead skin gently removed. This mutual relationship keeps reef fish healthy and helps control parasite populations.

Acropora coral

One of the reef’s most iconic builders is the Acropora genus of coral. These branching, staghorn-like corals grow rapidly and create complex structures that provide shelter for countless marine creatures. Acropora corals are essential reef architects offering protection, breeding grounds, and hunting spaces for fish and invertebrates alike. Their health is a strong indicator of a reef’s overall condition.

The Coral Reef Up-Close habitat, now open inside the Tropical Reef Aquarium, allows guests to see all these remarkable animals- and the coral they depend on- up close and learn more about their vital roles in reef ecosystems.
