Does coral get eaten by fish
Some fishes have an 'obligate' association with their coral prey, meaning the majority of their diet is centred on coral, and approximately one third of all corallivorous fishes fall in to this category. Other corallivorous fishes include coral as measurable part of their diet but also utilise other food items.
What fish chew on coral
Using their powerful beaks, parrotfish can munch on coral at an astonishing rate of 20 bites per minute. And what goes in must come out. If you swim behind a feeding parrotfish, you might spot a plume of fine sand coming out the back end – the digested remnants of a coral's stony skeleton.
Do corals protect fish
Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." About 25% of the ocean's fish depend on healthy coral reefs. Fishes and other organisms shelter, find food, reproduce, and rear their young in the many nooks and crannies formed by corals.
Why do fish need coral
Corals are extremely important in both commercial and local fisheries, as they offer protection for fish species and provide nutrients and food for the growth of juvenile fish.
Do small fish eat coral

Do fish like coral reefs

Can fish live without coral
There's a reason why coral reefs are known as the 'rainforests of the sea. ' Despite covering less than 1% of the ocean, they provide essential habitat for 25% (yes, one quarter!) of all marine life. That's well over 1 million species that live in and depend upon coral reefs around the world.
Can fish live in dead coral
More life can be supported by 'dead' coral rubble than live coral, according to a recent study. 'Dead' coral reefs supported 'cryptic' animals — hidden sea creatures, including fishes, snails, tiny crabs and worms — who hide under this rubble to save themselves from predation.
Why can’t you touch coral

What happens if coral dies

If too many reefs die, this can lead to the destruction of marine ecosystems and even the extinction of some fish.
Is it okay to touch dead coral

Is coral dead when it is white
When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
Is it OK to touch coral

Why can’t you break coral
Not only can this action expose the coral to pathogens, but the damage will also trigger a stress response. When corals are stressed, they will eject their zooxanthellae. This event is called “bleaching” because without the pigmented zooxanthellae the coral polyps lose their color and become white.
Do coral reefs feel pain
“I feel a little bad about it,” Burmester, a vegetarian, says of the infliction, even though she knows that the coral's primitive nervous system almost certainly can't feel pain, and its cousins in the wild endure all sorts of injuries from predators, storms, and humans.
