It depends on what you want to keep but yes. Sometimes you will need to feed because some nutrients are needed. My I suggest reviewing your QT process. Fish die but with proper QT and a disease free tank you can have fish survive many years with little effort.
Do fish affect coral reefs?
Unsustainable Fishing
55% of the world’s coral reefs are affected by overfishing. When fish populations decline, particularly those that feed on algae, algae can grow unchecked, eventually smothering corals.

How do fish help the coral reef?
Phosphorus in fish pee and nitrogen excreted through their gills are important nutrients for coral reefs to grow. In many reef communities, fish will take shelter in and around coral during the day — peeing out valuable nutrients — then forage for prey in and around the reef by night.
What happens if we lose coral reefs?
Coral reefs are known as “the rainforests of the sea” and provide a quarter of marine species with habitat and food. If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence.

Why are coral reefs important to marine life?
Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.
Does coral need saltwater?
Most reef-building corals also require very saline (salty) water ranging from 32 to 42 parts per thousand. The water must also be clear so that a maximum amount of light penetrates it. This is because most reef-building corals contain photosynthetic algae, called zooxanthellae, which live in their tissues.
Can you grow coral in a fish tank?
Corals thrive best in larger reef tanks but they can also be kept in small aquariums. One of my most favorite items in the marine hobby is soft coral.
Why are fish important to the ocean?
Fish play a far more important role as contributors of nutrients to marine ecosystems than previously thought. In a pair of articles, they show that fish contribute more nutrients to their local ecosystems than any other source — enough to cause changes in the growth rates of the organisms at the base of the food web.
How does ocean warming affect coral reefs?
A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment. Sedimentation runoff can lead to the smothering of coral.
How many fish depend on corals?
An estimated 25 percent of all marine life, including over 4,000 species of fish, are dependent on coral reefs at some point in their life cycle.
What fish depend on corals?
Many commercially important fish species, like grouper, snapper, and lobster, depend on coral reefs for food and shelter. The fish that grow and live on coral reefs are a significant food source for billions of people worldwide.
Are coral reefs alive?
Background. Corals consist of small, colonial, plankton-eating invertebrate animals called polyps, which are anemone-like. Although corals are mistaken for non-living things, they are live animals. Corals are considered living animals because they fit into the five criteria that define them (1.
What are 5 importance of coral reefs?
protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many marine organisms. are the source of nitrogen and other essential nutrients for marine food chains. assist in carbon and nitrogen fixing.
Why are coral reefs dying?
And they are dying. Coral reefs are under relentless stress from myriad global and local issues, including climate change, declining water quality, overfishing, pollution and unsustainable coastal development.
What happens if the sea dies?
The collapse of ocean bio-diversity and the catastrophic collapse of phytoplankton and zooplankton populations in the sea will cause the collapse of civilization, and most likely the extinction of the human species. And that is why when the ocean dies, we all die!
Is keeping coral hard?
Is it difficult to keep corals? Yes, some are quite hard to keep but some are not at all difficult. If you’re really interested in keeping corals you will need to get used to doing research on the corals you’re interested in keeping.

- Spread the word!
Do fish eat coral?
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.
Can you keep coral as a pet?
To enjoy coral as a pet, the first thing you’ll need to do is set up a specific saltwater tank that has temperature control, water flow and specific lighting. To create the optimal environment for your coral, you could work with a local pet store and consult online coral dealers, many of which offer customer support.
Can you keep coral in a tropical tank?
If you have artificial rocks, artificial coral or stones in your freshwater tank, and wish to keep them, these will be perfectly suitable to have in a marine fish tank.
Can coral reefs live in freshwater?
Corals reef life needs saltwater to survive and requires a certain balance in the ratio of salt to water. This is why corals don’t live in areas where rivers drain fresh water into the ocean (“estuaries”).
Can coral survive in freshwater?
Absolutely not! Live corals make stunning additions to marine tanks, cannot survive in freshwater and will gradually die off when placed in this environment. To make things worse, the corals will pollute your aquarium as they die, releasing ammonia and nitrates that can be harmful to your fish.
What are the conditions needed for coral reefs to grow?
- Sunlight: The vast majority of corals need to grow in relatively shallow water, where sunlight can reach them. …
- Clear Water: Corals need clear water to survive and do not thrive well when the water is opaque. …
- Temperature: Reef-building corals require warm water conditions to survive.
Are all corals toxic?
These decorative ornamental corals are commonly called ‘button polyps’, ‘sun polyps’ or ‘zoas’. Species of Zoanthid coral (e.g. Palythoa species and Zoanthus species) can contain a highly toxic, naturally-occurring and potentially lethal substance known as Palytoxin.
What do fish need to survive in the ocean?
Like other living creatures, fish must meet certain basic needs for survival. Water, food and shelter are among the most important requirements: Water: Fish not only live in water, but they get oxygen from water. They breathe by taking water into their mouths and forcing it out through gill passages.
What would happen to the ocean without fish?
A world without fish is a scary prospect. Without them, life as we know it will not be possible. The ocean will no longer be able to perform many of its essential functions, leading to a lower quality of life. People will starve as they lose one of their main food sources.
Why is marine ecosystem important?
Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
Is coral reef poisonous?
Is the coral reef poisonous? Answer 1: Some things living on coral reefs are, indeed, poisonous. Some kinds of pufferfish, starfish, lionfish, sea urchins, and sea anemones could be poisonous if you tried to touch or eat them–and these animals all live on coral reefs.
Can we grow coral reefs?
By breaking coral into smaller pieces, the marine scientists have been able to cultivate many more viable corals than would have occurred naturally. Once they are big enough, these coral seedlings can be transplanted onto damaged reefs in a process known as reskinning.
Why is coral fish important?
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.
What fish live in the coral reef?
More than 1,500 fish species live on the reef, including the clownfish, red bass, red-throat emperor, and several species of snapper and coral trout. About 5,000 species of mollusks live on the reef.
Can coral reefs survive warming ocean temperatures?
Coral reefs may be able to adapt to moderate climate warming and improve their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions.
Can coral reefs survive climate change?
Two of the world’s most ubiquitous species of reef-building corals seem surprisingly able to survive and even cope well with climate change, according to a new study—at least so long as global warming is kept below 2 degrees Celsius (3.6 degrees Fahrenheit), the target set by the Paris Agreement.
What does coral bleaching do to marine life?
When corals overheat, they react to the stress by expelling their algae, which results in coral bleaching. Bleaching leaves corals vulnerable to disease, stunts their growth, affects their reproduction, and can impact other species that depend on the coral communities. Severe bleaching kills them.
What is the relationship between coral and fish?
Another important mutualistic relationship is the one between coral and herbivorous fish. Coral provides shelter and food to herbivorous fish in return for protection from natural enemies, such as seaweeds.
Do clownfish live in coral reefs?
Clownfish habitat
Clownfish are commonly found in coral reefs and are prominent in the Indian Ocean, the Red Sea and the western Pacific, living inside of anemones in small colonies.
Can coral sting you?
Fire corals have nematocysts (barbed, threadlike tubes that deliver a toxic sting) and some have sharp edges that cause lacerations or abrasions. Over their diving careers many folks, including me, have experienced a sting or burning sensation from accidently touching or bumping into a fire coral.
Can corals 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.
Does coral have a brain?
Corals lack a brain but have a simple nervous system called a nerve net. The nerve net extends from the mouth to the tentacles.
How do coral reefs clean water?
Water filtration
Coral reefs help keep our near shore waters clean from pollution. Many corals and sponges are filter feeders, meaning they consume particulate matter (pollutants that do not dissolve in water) in the water.
What do coral reefs eat?
Corals get their food from algae living in their tissues or by capturing and digesting prey. Most reef-building corals have a unique partnership with tiny algae called zooxanthellae. The algae live within the coral polyps, using sunlight to make sugar for energy.
Do coral reefs produce oxygen?
Just like plants, providing oxygen for our earth, corals do the same. Typically, deep oceans do not have a lot of plants producing oxygen, so coral reefs produce much needed oxygen for the oceans to keep many species that live in the oceans alive.
Why should we care about coral reefs dying?
Coral reefs are important for providing many essential services for humans and for biodiversity. It supports a tremendous amount of biodiversity for taking up a relatively small part of the ocean. Coral reefs make up only 0.1% of the ocean floor and host millions of species.
Will the ocean be empty by 2048?
It is unlikely that the oceans will be empty of fish by 2048. Although experts disagreed on the effectiveness of the Seaspiracy documentary to help protect the oceans, they all agreed that overfishing is a major issue.
Can human live without the ocean?
Without healthy oceans, our life on Earth would be severely challenged, unpleasant and perhaps impossible. The oceans are the life support system of all living beings. That’s because life on Earth can thrive without land, but it cannot exist without an ocean.
Will fish become extinct?
According to study seafood could be extinct in the next 30 years. A study from an international team of ecologists and economists have predicted that by 2048 we could see completely fishless oceans. The cause: disappearance of species due to overfishing, pollution, habitat loss and climate change.
What would happen if coral reefs died?
Coral reefs are known as “the rainforests of the sea” and provide a quarter of marine species with habitat and food. If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence.
How many coral reefs have been destroyed 2020?
The latest reports state that as much as 27 percent of monitored reef formations have been lost and as much as 32 percent are at risk of being lost within the next 32 years. For marine biologists, the destruction of the reefs has proven to be as frustrating as it is heartbreaking.
Why are there no coral reefs off the coast of California?
Coral reefs are either restricted or absent from along the west coast of the Americas, as well as the west coast of Africa. This is due primarily to upwelling and strong cold coastal currents that reduce water temperatures in these areas (Nybakken, 1997).
How do fish survive in coral reefs?
Why do so many fish live near coral reefs? Because of warm water and abundant food supply, coral reef communities are bustling with life. Reefs with their bush like shape offer many nooks and crannies for fish to hide in. Small fish can hide from big predators inside a coral reef.
Do fish protect corals?
The study found that fish mitigate coral bleaching by providing benefits to the zooxanthellae (Symbiodinium) that normally live within coral polyps. Through photosynthesis, these Zooxanthellae provide food for the coral polyps that they live within. Coral bleaching occurs when stressed corals eject the zooxanthellae.
Do fish destroy coral reefs?
Unsustainable Fishing
55% of the world’s coral reefs are affected by overfishing. When fish populations decline, particularly those that feed on algae, algae can grow unchecked, eventually smothering corals.
