Motu Nuhi-Nuhi (l’aquarium)
Why dive here
With 146+ marine species recorded in the area - including blacktip reef sharks, dolphins, giant moray eels, octopuses and sperm whales - Motu Nuhi-Nuhi (l’aquarium) offers some of Rangiroa's richest wreck diving. Water ranges 27-29°C, warmest February, March, April.
Motu Nuhi-Nuhi, affectionately known as ‘the Aquarium,’ sits snugly in the Rangiroa lagoon, a short boat ride from Tiputa Pass. We love it for its easy-going vibe and sheltered conditions, making it perfect for a relaxed dive, especially if you’re getting back into things or just want a chill afternoon. The reef here is shallow, topping out around 14 metres, and it’s always protected from any strong currents. Drop in and you’re immediately enveloped in a vibrant coral garden. We’ve drifted over sandy patches dotted with coral bommies – often called ‘potatoes’ here – absolutely teeming with smaller lagoon fish. Look out for the flash of Pinktail triggerfish, the bustling Six-line wrasse, and the occasional Golden trevally cruising by. The visibility averages a comfortable 17 metres, giving you plenty of light to spot creatures like the tiny Nocturn Goby peeking from its hidey-hole or a sleepy Bottleneck Sea Cucumber resting on the sand. It’s a gentle dive, letting you linger and really soak in the details. This site is exactly what you need for a no-stress immersion, ideal for beginners, photographers taking their time, or anyone wanting a serene dive away from the stronger currents of the passes.
