The Aquarium
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
The Aquarium earns its unimaginative name every single day: coral heads on white sand in knee-to-house depths of glassy lagoon water, mobbed by fish that have learned boats mean interest rather than harm. Butterflyfish, snapper, and juvenile Napoleon wrasse crowd visitors; blacktip reef sharks patrol the sand at a polite distance; moray eels tenant the heads. Operators run first-timers, refresher dives, and snorkel drops here, and the site absorbs the traffic in stride. For divers back from the passes with adrenaline to spare, it is also simply a pleasant place to float and let the lagoon demonstrate its colors.
The moment you come for: Tame, dense reef-fish crowds; blacktips over white sand; ideal first-dive and snorkel conditions.
Topography: Coral heads and sand inside the lagoon, shallow and bright
Current: A little pass-driven movement at tide changes; otherwise gentle.
Entry: A few minutes from the Tiputa-side docks, inside the lagoon near the pass mouth; moored entries in calm water.
Know before you splash
Hazards: Boat traffic near the pass; mild current at tide turns.
Conservation: Fish here are habituated, not fed by rule-abiding operators — keep it that way; no touching, no bread.
