There is, however, quite a bit of scientific evidence that suggests providing alternative sources of nutrition (feeding) your corals does increase growth rates and improve natural coloration. Naturally, corals do collect suspended particles of food from the water and/or absorb dissolved nutrients through their tissue.
How to make corals more colorful?
Color is enhanced by healthy corals and the correct lighting mainly. Granted first they have to be healthy. Amino acids and reef snow (spot dosed is better but I sometimes just dump it in) is about the only thing you need for photosynthetic corals. Remember that most corals are brown in the ocean and so your lighting is what makes them pop.
How to increase coral growth in aquarium?
Coral growth can be increased by getting a mix of factors right. These include water conditions, lighting, and a healthy diet. Corals should be acclimated first to tank’s conditions before they grow properly. The growth of the corals is determined by how perfect tank conditions are.
What do you feed your corals?
Along with kepping up the big 3 (calcium, alk, mag) your corals need food!! They get indirect food from the microfauna growing in your tank,but you can boost color and growth by directly feeding them. Oyster eggs and gut-loaded rotifers are the best IMO. Just watch how much you feed because it can create nutrient problems.
Why do corals turn brown?
In general, corals, particularly hard corals such as LPS and SPS are very dependent on this algae. Without it, they won’t be able to survive too long. However, the zooxanthellae are the reason why corals turn brown. Let me explain why. These marine algae contain chlorophyll, a pigment responsible for the color of the corals.
How can I make my coral more colorful?
Using lights with peaks in the red, blue, pink and yellow spectrums will ensure many different colours are displayed, if already present in your corals. Using a little activated carbon regularly in a reef aquarium will remove any discoloration to the water, which would prevent the colours of your corals showing true.

Why is my coral losing color?
Coral reefs are bright and colorful because of the algae that live in them. When water temperatures rise too high, the algae are forced out of the coral, causing the reefs to lose color and potentially die.
What affects coral color?
So, what does this mean? Essentially, the number of zooxanthellae and the amount of chlorophyll affect coral coloration.

What color light is best for coral?
For optimal coral growth, you will generally want a full spectrum of light that includes some reds, oranges, and yellows, but that is heavier towards the blue range.
Is green light good for corals?
Green light has not been shown to produce biological effects in terms of energy usage and growth. In other words the coral may not be getting anything useful from this light and it may not help the coral grow in any way. However, green light does produce a biological effect in terms of color.
Do corals need white light?
Corals don't need a white light to grow in your reef tank. Instead, they need blue light to grow healthily. White light is more useful to humans, as it helps them 'see' the corals in the reef tank better.
What makes coral pink?
Coral is a mix of red and orange, which ultimately means red and yellow, lightened with white. You can get coral by blending 3 parts rose-pink paint and 2 parts yellow paint, or, get back to basics, and mix 1 part clear orange, 1 part rich red and 2 parts white to lighten things up.
What makes coral red?
Anatomy. In common with other Alcyonacea, red corals have the shape of small leafless bushes and grow up to a meter in height. Their valuable skeleton is composed of intermeshed spicules of hard calcium carbonate, colored in shades of red by carotenoid pigments.
What shade of color is coral?
pink-orange colorCoral is a pink-orange color that gets its name from marine invertebrates decorating the bottom of the sea. It is fresh, invigorating, and feminine. The coral hex code is #FF7F50. A dynamic and vibrant color, coral is particularly stunning when combined with tiffany blue and white.
Can you bring coral back to life?
Dead Reefs Can Come Back To Life, Study Says Rising water temperatures and increasing ocean acidity can kill coral reefs. But a new study finds that dead reefs can potentially recover from catastrophes if ocean temperatures stabilize. Some scientists say the resiliency of coral reef may be the key to their survival.
How long does it take coral to recover from bleaching?
“We found that the time needed for coral reefs to recover from bleaching is at least 9-12 years - if there is no new disturbance in the meantime, such as a cyclone or re-bleaching,” he said. Dr Wolanski said the conditions that promoted recovery in different species of coral varied across the species.
Can a bleached coral recover aquarium?
While possible, severely bleached corals often do not recover, and they die.
Why is my coral turning brown?
The Cause: Corals typically turn brown as a result of the overproduction of zooxanthellae (a type of algae) inside of a corals tissue. As zooxanthellae levels increase, they block the coral's natural pigments causing them to turn brown.
Do I Need To Feed My Corals?
It is not 100%, absolutely necessary to feed your corals because they get most of their energy via photosynthesis so all they really need is an appropriate light source.
Types Of Coral Food
Choosing the right size and type of food for your particular corals is important to ensure your corals can actually acquire the food. Most of this is based upon particle size because corals with smaller polyps like an Acropora (SPS) cannot consume larger particle size foods as you find on many LPS corals.
Coral Feeding Tools
Mixing container - small cup to dissolve frozen foods or mix foods with tank water for broadcasting feeding.
Don't Overfeed!
It's easy to overfeed your corals because they cannot move around and catch the food like your fish. The food must come to the coral via the water flow or target feeding.
Feed Corals At Night
Many corals actively feed upon suspended foods at night. In your tank, you might see corals shapeshift each night as they display their "feeding response". This might look like long feeder tentacles waving in the flow, the uptake of extra water resulting in swollen flesh, or the release of clear slime designed to capture prey.
How To Feed Corals
Use some kind of syringe or squirt feeder to draw up the food/water combo and squirt it directly onto the corals. This is referred to as target feeding because you are targeting the individual coral. This is the most common approach because you can more effectively deliver the food with less waste in your filtration.
Why do corals change color?
This color acts as a "sunscreen" when the coral is experiencing very high levels of photons. If you have ever seen your corals change colors from their original it is due to a higher expression in specific chromoproteins.
What type of light do corals use?
UV excitation- There are three types of ultraviolet light that corals will harness. UV-A,B, and C. UV-A is the only UV light that can safely be harnessed by corals. UV-A will excite almost all wavelengths of color, however, extended exposure will cause the zooxanthellae to become mutated (via thymene dymer) The ozone layer in the earth's atmosphere absorbs almost all UV-C and greatly lowers the amount of UV-B that passes through. Metal halides emit UV-A,B, and C so these wavelengths will excite your corals but may be detrimental over extended periods of time due to the mutations caused to zooxanthellae and coral pigment proteins from UV-C and UV-B light.
What is the color of coral?
background: color is typically thought to be derived primarily from zooxanthellae algae. Although they can contribute to the color, the proteins the coral produces are more related to the color. zooxanthellae typically are brown so they can absorb the widest range of photons for photosynthesis.
How many micromoles does coral absorb?
In typical hobbyist aquaria the average PAR reading is 150 micromoles/m2/L, as compared to the sun: upwards of 1000 micromoles/m2/L It has been demonstrated that corals only barely perform at these "subpar" levels. A graphical representation of the effectiveness of photosynthesis (color emissions) and intensity shows that there is very little incline in productivity until just before 400 micromoles/m2/L. At this point the productivity increases exponentially and then plateaus through 700+ micromoles/m2/L.
What wavelength is the best for zoas?
This is typically found in zoas. Their optimal color can be observed by producing very specific wavelengths in the "blue" light range (460-520nm)
What is the most important aspect of a reef system?
Lighting: of all the aspects essential in a reef system, flow, nutrients, placement, water quality, and lighting, lighting is the most significant.
Do corals have zooxanthellae?
This data clearly states that by supplying a higher intensity of light than typically observed in home aquaria coral is able to express their desired "colors" based upon fluorescent proteins, non-fluorescent proteins, and chromoproteins, and not zooxanthellae. This means that the corals will have their natural color, which acts to attract zooxanthellae to them. The corals will control their contractions of the tissue to ensure that they get the most advantageous use of the high intensity light and the zooxanthellae will only photosynthesize in lower-light conditions. This means that your corals will color their true colors while under high intensity lighting (400+ micromoles/m2/L) and have no outside influences on which color is being reflected. This moderate regulation of zooxanthellae by the coral allows a crisper cleaner color for your viewing pleasure.
What color can you mix to make coral?
Based on the color theory, you can mix red, orange, and white to get coral. Adding the white on the latter lets you achieve a peachy color, with less orange.
What color is coral?
Because coral is a pastel color, it can easily blend with other hues. In interior design, coral looks great with yellow, pink, and neutral colors white and gray. It balances out other colors, which make coral a playful and easy component in interior design.
How to make yellow?
Yellow can be made by mixing red and green. Then for red, you can mix magenta and yellow. From the primary colors, you can create secondary colors by mixing red, blue, and yellow together. To achieve the secondary color green, you need to mix blue and yellow. For orange, simply mix red and yellow.
What can you do with mixing colors?
By mixing these colors, you can expand your color palette knowledge and use it when painting and doing other forms of artwork.
What does coral look like?
You might also associate this color with curtains and leaves during autumn. Sometimes, coral can also look like pink with a pigment of orange. It is vibrant, playful, and depicts nature.
How to get violet color?
For orange, simply mix red and yellow. Meanwhile, you can get the color violet by combining blue and red together. Part of color experimentation is adding different quantities of primary and secondary colors to achieve tertiary colors.
Can you mix yellow and orange to make coral?
Take note that you need more yellow to achieve coral, otherwise, the mixture will become orange. You’ll have to experiment with different color quantities to achieve your desired coral hue. But ultimately, you can mix the colors red, white, yellow, and orange to make coral.
Factors you must get right for optimum coral growth
Corals are sensitive organisms and heavily rely on an optimum set of tank conditions for them to thrive and grow faster. If those conditions are met by any means, then coral will grow exquisitely and lay the further ground for other corals to get acclimated with the current tank condition as fast as possible.
Lighting can play an important role in coral growth
Most of the corals kept in a reef tank are photosynthetic, and these rely on light for their energy needs. Symbiotic algae within the reed tank use that light to prepare food and provide nourishment to corals, and corals, in return, provide algae with protection and Co 2 for photosynthesis.
Using the right mix of nutrients and a healthy diet to boost coral growth
Photosynthesis can only take care of so much nutrition that corals require, and that is why you must provide them with a healthy diet for them to thrive properly. Most of the corals are hunters, and they eat by catching the nearby floating animals known as zooplanktons.
Water flow can help corals reach their maximum growth rate
Corals don’t breathe or excrete as fish do. Freshwater fish can use their gills to respire through water and directly excrete the waste that it has produced into the water. On the other hand, corals require a consistent and robust flow of water to make this happen.
Final Thoughts
If you wish to see intense color on your corals and increase their growth, specific parameters such as light, food, nutrients, and water flow are key here. Everything takes patience and time, and it is the same with maximizing coral growth; it will happen but slowly and over time.
Do corals eat polyps?
BTW some people still believe corals don't eat. They do (they have polyps and mouths for a reason). Nutrients in the water feed the zooxanthellae but the coral needs supplimental food as well. I'll believe it when scientists can actually find some way the polyps digest and absorb nutrients from whatever they catch.
Do corals eat zooxanthellae?
