Aquarists can occasionally see the coral spawning in their closed system, but it is not controlled by the system, it’s more of happenstance but Innoqua has researched how they can manipulate coral spawning in the aquarium. In Japan, corals are spawning once year around June but what Innoqua achieved is to make Montipora digitata spawn in winter by controlling the water temperature.
Corals grown in an offshore “coral nursery” at Fitzroy Island on the Great Barrier Reef have spawned for the first time, four years after being planted.
