Can you have coral with tropical fish?
It's not recommended to place coral or any type of sea shells in a tropical fish tank. Doing so can increase the water's hardness, and may stress the fish. Not all fish like hard water. Plus, coral is a living thing, putting it in freshwater would kill it.

They chew off chunks of coral and 'poo' out the calcium carbonate of the coral as a fine sand.

All tropical fish need light, as they tend to live near the surface around coral reefs. It is no different if the fish is kept in a tropical fish tank. Too much light duration will result in excessive algae growth in a fish tank. Therefore, light duration should be regulated to keep algae growth to a minimum.
Parrot fish have a specific niche on tropical coral reefs as they have teeth which allow them to eat coral. They either scrape algae off the coral or eat chunks of coral and digest to get to the algae. The remains are then excreted as sand. They will also eat other microorganisms that lives on coral. This specialisation means that there is little competition for their particular foodstuff. Thank you! That is my answer!
The word tropical simply means that something is from the tropics; ie, near the equator. There are two kinds of tropical fish; tropical freshwater and tropical marine. When someone says 'tropical fish' in a pet store, or in the context of an aquarium, they generally mean tropical freshwater. Marine fish are simply fish that come from the ocean, ie, they are saltwater fish.
