Fish & Aquariums: What You Need To Know About Your Aquarium'S Water Temperature (And Its Coral Life Span)
The optimal temperature for coral to thrive is between 73 and 84 degrees F. Most coral reefs are found where water temperatures are between 80 F and 89 F. The zooxanthellae algae, which most corals need for survival, will die or vacate the coral. Most aquarium corals are collected from the Indo-Pacific, Caribbean and Red Sea. The higher water temperatures in saltwater (and freshwater, too), the less dissolved oxygen it will hold. Dried oxygen levels in seawater are about 20% less than in freshwater. Fish & Aquariums is a trade association for fish and aquariums. It was founded in 1881 and is based in Washington, D. C. It has more than 1,000 aquariums in the U. S. and around the world. . . .
