It's because reefs are built by salt water animals.
Coral reefs are salt water Ponds are fresh water
Only salt water not brackish or fresh fresh and brackish water kills the polyps
Coral reefs are found in saltwater environments such as oceans and seas. They require a specific salinity level to survive and thrive, which is not typically found in freshwater environments.
Because of the mixture between fresh water and salt water.
they actually like both:)
why do coral reefs can live in salt water
I wouldn't think so as goldfish can't live in salt water.
no there are no tadpoles in the coral reef they can not live in salt water
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
on fresh salt water
Salt water is water that has salt in it and it is found in oceans. Fresh water does not have salt and is found in rivers and lakes.
Coconut trees prefer to grow in soils that are well-drained and not saline. Although they can tolerate some exposure to salt water, they primarily rely on fresh water for optimal growth and fruit production.
