Peppermint angelfish on deep dive in Rarotonga

Mixed gas rebreather diving

We store helium to blend trimix diluent for experienced mixed gas CCR divers who are interested in exploring and diving Rarotonga’s hidden submerged treasures. Beyond 70 meters, Rarotonga’s deep drop offs fall straight into the abyss and offer fascinating marine life. The type of corals change and you find massive sea fans as well as colourful soft corals which you won’t see anywhere on Rarotonga within recreational diving depths. Here you also find various fish species that you find pretty much nowhere else in the world. Amongst these fishes is the holy grail of tropical saltwater reef fishes, the Peppermint Angelfish (Paracentropyge boylei), highly sought after by aquarium enthusiasts. Other rare, deepwater reef fishes on Rarotonga are, for example, the elusive Narcosis Angelfish (Centropyge narcosis) and the Pitcairn Angelfish (Genicanthus spinus).

Seafan and soft coral on deep rebreather dive on Rarotonga

Apart for the smaller, rare species, you will often encounter tunas and schools of trevallies when conducting deep drop-off dives in Rarotonga. On the south coast, reef shark encounters are frequent on deep mixed gas dives. There is also at least one shipwreck on Rarotonga that lays within technical diving limits, hopefully more will be discovered soon.
