Check the phosphate levels in the reef tank. Phosphate levels that are too high might cause corals to die off slowly or lead to the death of newly imported, delicate species such as SPS corals. Use a phosphate test kit to determine how high the phosphate concentration is, and then reduce it using phosphate remover and regular water changes.

Why are my soft corals shrinking?
What Effects Do Variations in Lighting Have On Corals? These zooxanthellae are responsible for giving coral polyps and tissues their characteristic colors. We are able to exert some degree of control over the final coloration and shading of our corals by adjusting the spectrum output of the lights in our aquarium.
- How? Let’s imagine that up until now, we’ve been working with a 5500K VHO fluorescent system that draws 220 watts of power.
- We feel that urge to spend money, and we think that putting a 250-watt metal halide with a 10,000K bulb will improve both our tank and the creatures in it.
- In addition to the visual value of the rippling light display that these lights produce, we have unexpectedly altered the frequency of light to which all of the creatures that are part of our system have been accustomed.
We characterize the change in CRI or spectral output using the term “frequency,” which stands for frequency. When corals experience a rapid and significant shift in the source of the energy they get, they frequently react by contracting, which can be seen as a sign of discontent on their part.
- This sudden shift in appearance is being brought on by the recoiling of billions of symbiotic algae, which are sending shock waves through their host and are responsible for the phenomenon.
- Within a matter of days, and even hours in some cases, the zooxanthellae will modify their ability to absorb light of this new frequency and intensity by altering the color of their overall appearance.
That’s true, the color of the coral is really that of its hitchhiking algae, which adjusts its pigmentation in response to changes in the amount of UV light and other factors related to its source of energy. Have you ever seen a Tridacna clam from the highest point of the aquarium, only to be dissatisfied when you lowered your head and looked at it from an angle? How come the hue of the clam looks so drab when viewed from the side, yet when viewed from above, all of its rich and brilliant colors seem to be screaming at the sky? That would be the zooxanthellae algae living inside the clam doing their thing and preventing the clam’s delicate tissues from becoming sunburned.
When the lighting is altered in any significant way—and don’t be fooled, because even replacing old tubes or lamps with new ones that have the exact same wattage and URI can produce the same reaction, if the old tubes have been allowed to degrade past the point where their useful spectral output—the system must be given time to gradually adapt to the new conditions.
How? In most cases, light and tube replacement takes place right after the system is powered down for the night. After that, I either swap out the old for the new or replace it entirely. The next morning, I make sure that not all of the lights turn on at the same time by leaving gaps between the different types of tubes.
- This task will be much simpler to do if you install a dimmer circuit similar to the ones that are found on certain electronic ballasts.
- However, this won’t be possible if you just have a two-tube system to work with.
- It is important to keep in mind that corals and the zooxanthellae that live within them adapt to changes in their environments in the same way that people do.
These creatures do not have the same luxury that humans do of being able to shield our eyes from the harsh sunshine. They have no choice but to react in the only way they know how, which is to retreat and gradually get back to acting normally. It is interesting how we can’t talk about lighting without getting into the real physical qualities of the coral, aren’t you going to agree? After all, this is the major reason why there is any kind of illumination at all!
Why do all my corals keep dying?
Are your corals dying? The four causes and solutions for saving your corals and reef tank
Just as a change in temperature may lead to the unexplained death of corals, so can a change in a number of other factors, most notably alkalinity. Wide fluctuations in a number of these parameters can have the same effect. As we have gotten better at measuring the parameters of our tanks, and as some of us have gotten to the point where we measure certain parameters frequently or have monitors that test almost continuously, we have realized how negatively our corals can be impacted when there are large swings in the parameters of their tanks.
- When corals pass away for what appears to be no apparent reason, it is possible that more frequent testing during the course of a day is required to determine whether or not this was the cause of their demise.
- As is the case with temperature, most corals are able to tolerate small daily swings; however, significant fluctuations, such as pH shifting by more than one point during the day/night cycle or alkalinity shifting by more than two to three points every day, can cause the corals to experience enough stress to cause their death.
One further point to consider in relation to testing is the likelihood of severe human error when test kits are not used frequently. In addition, the majority of test kits become useless after a certain amount of time has passed. Consequently, if it does not appear that swings are occurring or if the water levels are within range, then these aspects need to be investigated.
Can dead coral come back to life?
The atmosphere on October 9th, 2019 The consequences of climate change are starting to be felt by coral reefs. Images & Stories / Stock Photograph from Alamy It is possible for reef-building corals to make surprise recoveries from the devastation caused by climate change.
- It has been discovered that certain corals only appear to be dead when they are placed in water that is exceptionally warm.
- Instead, the coral polyps will contract and withdraw into their rigid skeleton, giving the appearance that the reef has died.
- They will then recolonize the skeleton when conditions become more favorable.
It is a survival strategy that has never been observed previously in corals of today; nevertheless, if the environment continues to change, it is possible that it will not assist the corals. Warming oceans have been extremely damaging to coral reefs. Reefs all across the world, including the Great Barrier Reef, are dangerously close to being destroyed.
Cladocora caespitosa, a species of the rare genus Cladocora that has a sluggish growth rate, is especially susceptible to extinction, and there is no evidence to suggest that it may rebound. Researchers Diego Kersting and Cristina Linares from the University of Barcelona in Spain have found that it is feasible for C.
caespitosa colonies to recover after 16 years of monitoring the situation in the Mediterranean Sea. They made the startling discovery that corals that appeared to be dead were actually capable of regrowing in spite of the heat damage brought on by climate change.
- A few of them came very close to making a full recovery.
- Kersting and Linares discovered that when a C.
- caespitosa colony is exposed to warm weather, the polyps that make up the colony contract and withdraw deep into the coral skeleton.
- The stony coral seems to be devoid of any form of life when seen directly.
However, given enough time, these small polyps, which are what give coral its recognizable “tentacles,” may renew.
How do you promote soft coral growth?
Water Flow Despite the fact that corals do not exhale or defecate in the traditional sense, they nonetheless need a sufficient amount of water flow in order to remove waste and maintain respiration. A healthy flow of water not only helps wash away trash but also brings in new oxygen.
- Different corals have various requirements for the amount of water flow that they need, similar to the lighting needs.
- Soft corals that do not have a stony structure have the lowest flow requirements, whereas SPS corals, also known as small polyp stony corals, have the greatest flow requirements.
- Additionally, the flow of water must be both unpredictable and indirect.
When a water jet is pointed directly towards corals, it is not good for the corals’ health. In its place, they choose a flow pattern that is very variable, with water arriving from a variety of directions at a variety of times and with varying intensities.
Keeping corals alive is a problem, and increasing the amount of coral that grows is an even more significant task. The cultivation of corals with extremely vivid coloration is an even larger problem. In a reef aquarium, increasing coral development and color requires maintaining appropriate and consistent amounts of light, food, nutrients, elements, and water flow.
This is the key to achieving this goal. Just keep in mind that nothing worthwhile ever occurs quickly.
What light do soft corals need?
Preserving the Good Health of Soft Corals – The majority of soft corals thrive best in aquariums that have a reasonable amount of light. When the aquarium is lit by lights of a high intensity, the corals should be put towards the bottom of the tank, but when the light source is dimmer, they should be placed at the top.
Water Flow: The ideal water flow for soft corals is moderate to low flow; this current offers circulation that allows food to be pushed over the corals, but it is not so powerful that the corals cannot open. Chemistry of the Water Soft corals have a high tolerance for changes in the chemistry of the water inside a tank, which is one of the primary reasons why they are such a good choice for beginners.
Feeding: Soft corals like to eat a little bit of food as well, so if your aquarium is a little bit unclean, it might provide them with an excellent supply of food. Regardless of the level of cleanliness of the water in the tank, as long as the temperature is maintained between 72 and 76 degrees Fahrenheit, soft corals are able to grow.
What does healthy coral look like?
Olive green, tan, brown, and a very light yellow are the colors that healthy coral can take on. A disease or bleaching will not have any effect on any section of a coral colony that is healthy.
Are soft corals hard to keep?
Are you in the process of setting up your very first saltwater aquarium and looking forward to getting your hands on your very first corals? If this is the case, soft corals are a wonderful kind of corals since they are simple to maintain and are very appealing to the sight.
Stony corals belong to the order Scleractinia, whereas soft corals belong to the order Alcyonacea. These two orders are distinct from one another. It should go without saying that soft corals are, in fact, soft; but, if you were to look at an Acanthophyllia, you may mistake it for a soft coral. The majority of soft corals, in contrast to hard corals, do not generate an internal skeleton and do not build the reef.
However, scientists have recently found that soft corals contribute more to the formation of reefs than was previously believed. Sclerites are the tiny needle-like support structures that are seen in soft corals instead. The sclerites of Sinularia are seen here in enlarged form.
Reef keepers admire the flowing look of soft corals because of their flexibility and their ability to bend with the water. Some, like Xenia, even have a pulse, and if you’ve ever gone SCUBA diving in areas like Fiji, you’ve probably seen the breathtaking fields of Dendronephthya there. The majority of soft corals in aquariums thrive best with moderate light.
If you have bright lights, you may put them at the bottom of your tank; if you have softer lights, you can put them at the top of your tank. Either way, they can be used in either location. The variety of hues and structures that may be discovered are showcased in this Aquamedic tank that is dominated by soft coral.
- The fact that rocky corals are more sensitive to changes in the chemistry of the water than soft corals is one of the reasons why soft corals are called starter corals.
- Because soft corals also appreciate a little bit of food, it is okay for your tank to be on the somewhat dirty side if it is.
- These kinds of corals do well in water currents that are moderate to low.
A current that is not so powerful that it inhibits the corals from opening is said to be moderate. A moderate current offers circulation that allows food to be swept over the corals and provides circulation. Soft corals, like other types of coral, require a salinity of 1.025% or 35 parts per thousand and water temperatures between 72 and 76 degrees Fahrenheit (22- 24 degrees Celsius).
- Keep in mind that these are the criteria for photosynthetic soft corals, and that the requirements for non-photosynthetic soft corals like Dendronepthya are far more challenging than for practically any other coral.
- The resilient and widely available soft coral known as cabbage leather is an excellent choice for novices.
It appears that a somewhat greater nutrient content, such as that which is present in reef aquariums that are just getting started, is really beneficial to soft corals. Therefore, provided that the appropriate circumstances are met, soft corals will multiply at an astounding rate, and before you realize it, your aquarium will be overrun with them.
- Therefore, use caution and do not allow one to get out of control since it can grow on top of other corals, and particular types of soft corals can sometimes be regarded to be a nuisance.
- Xenia has colonized every available space on this reef in Venezuela.
- Soft corals are the easiest type of coral to care for, and they are the beginning point for anyone who wants to get into reefing.
The upkeep that is required for soft corals is rather low, they mature rapidly, and there are a great many different color and texture combinations available for them.
What should I feed my soft corals?
The Coral Foods Company. The terms phytoplankton and zooplankton are together referred to as plankton. Phytoplankton is a kind of algae that is tiny and filled with nutrients. This is not a single species of algae but rather a huge collection of diatoms and dinoflagellates that together make up the microalgae.
- A broad variety of marine organisms, such as clams, feather dusters, corals, zooplankton, and others, rely on phytoplankton as their primary source of nutrition in the ocean.
- The term “zooplankton” refers to a wide variety of aquatic organisms ranging from microscopic to quite small.
- These include species like copepods and brine shrimp that will stay zooplankton for the entirety of their lives, as well as animals that are only considered zooplankton for a portion of their lifetimes (the larvae stage of most fish, snails, and clams.) Rotifers, copepods, brine shrimp, and mysis shrimp are all examples of common zooplankton that are utilized in the process of feeding corals.
There is a wide selection of frozen coral diets available in aquarium and pet supply retailers. Meaty meals such as brine shrimp, chopped clams, chopped shrimp, cyclops, krill, mysis shrimp, silversides (small entire fish), rotifers, zooplankton, and others are included in this category of foods.
In addition, there are frozen coral feeds that contain a combination of phytoplankton and zooplankton that are very small. Many of the frozen meals that have been described are also utilized as sources of nutrition for fish and invertebrates. Some frozen meals include a mixture of several kinds of foods in a single container that is meant to be consumed by corals, fish, and invertebrates as a source of nutrition.
Because of this diet, the water will get contaminated with a wide variety of particles of varying sizes. Live foods, preserved foods that were once alive, and customized mixes are all examples of liquid foods. Live food and the majority of the foods that have been preserved include organisms such as phytoplankton, copepods, oyster eggs, and rotifers.
Foods that imitate the natural marine snow found in the ocean are included in the category of liquid speciality blends. These blends, along with a variety of other combinations of food and matter, are intended to be consumed by filter feeders. Dry coral diets consist of dried phytoplankton, zooplankton, and krill, in addition to a wide variety of other types of seafood.
There are also unique formulations of coral food available.

On the substrate, I make out some traces of crimson. I’d prefer not point the finger at the hypothesis of insufficient nutrients. It has been my experience that maintaining their health requires not only feeding them but also providing them with a somewhat reduced light and flow. Mind you, I wouldn’t stuff myself silly.
