How would you classify the relationship between the different species of coral?

The relation between different species of coral can be classified into mutualism and competition.

Explanation:

Coral is an animal the can live and reproduce in a hard surface underwater where the water is warm and shallow. They reproduce sexually and produce larvae. Coral larvae move with the water current and grow in hard stratum where the sea water is warm. Corals feed on plankton and on other corals. They compete for space or live in mutual association with one another.
