Golden damselfish prefer steep sections of the reef, either on the outer fringes or near drop-offs with steady currents. Their bright yellow coloration makes them stand out. Mated pairs occasionally lay eggs near Blacktip Reef's underwater viewing window. When this happens, you might see the male hanging out nearby to guard the eggs.

Some fish swim, some bury themselves, and some, like the longnose hawkfish, perch. This fish alights on shelf corals and sea fans, using its fins to wedge itself into crevices. These fish are not the best swimmers, in part because they lack swim bladders. Instead, they swoop from their perches to catch food as it passes by.

The black-tailed dascyllus' high-contrast stripes make its shape harder to discern against the coral backdrop, especially from further away. They stick close to specific corals, rarely venturing out, and graze on any overgrowing algae, as well as munching on the fish flakes and small shrimp that aquarists provide.

Queensland groupers are among the largest bony fish known to live on reefs. Despite their hefty size (they can reach lengths of 7 feet or more and weigh up to 880 pounds!), they can be reclusive. The grouper in Blacktip Reef is usually found in the deepest part of the habitat. Its mottled grey colors make it harder to spot when peering into the depths.
