Why does it take a long time for coral reefs to grow?
Reefs themselves grow even more slowly because after the corals die, they break into smaller pieces and become compacted. Individual colonies can often live decades to centuries, and some deep-sea colonies have lived more than 4000 years .
Do coral reefs grow slowly?
From these rings scientists have found that corals grow very slowly, at a rate of only 1 to 10 cm (. 4 to 4 inches) per year, and that some coral colonies are hundreds to thousands of years old.

Coral frags don't grow fast in a reef tank. Rather, the growth can be quite slow. For instance, massive corals tend to grow at a very slow rate of about 0.5 – 2 cm (0.2 – 0.8 in) per annum. It takes a few weeks for a coral frag to establish itself, and specific growth rates depend on the species.
