Tonga is one of the furthest south tropical places that corals
and fish are shipped from. There is an exceptionally deep trench,
the Tonga Trench, over 30,000-feet deep near the islands.
There are cold water, nutrient-rich upwellings and great sea bird
nesting colonies, which fertilize the land and sea.
The water temperature is a cool 75-degrees F.
Tonga is a great place to order Acropora and many of the SPS corals,
LPS types, such as Brains and Acans, and soft corals, such as Leathers.
They have a limited diversity, with much of it endemic, but the
quality is excellent.
