Favia Coral is a hardy and inexpensive aquarium coral that is suitable for beginners and attractive enough and tolerant enough to warrant space in an advanced reef keeper’s tank, too. They are part of the well-known “Brain Coral” family. Let’s dive a bit deeper into the ins and outs of having a happy Favia coral.

Favia coral identification: How to know your Favia from your Favites
Favia and Favites are two closely related genera of LPS corals. Telling them apart is a challenging task. They both have similar appearances, feeding habits, and care requirements. Both Favia and Favites corals are massive (grow as a mound vs. encrusting or some other growth form) large polyp stony corals and larger colonies are round or dome-shaped. The main difference between the two genera is that corallites of Favites share a common skeletal wall, whereas the corallites of Favia have two distinct walls. Sometimes, it may actually require a detailed analysis of their coral skeleton, to be certain.
Note Favia colony, on the left, has distinct walls around each individual corallite vs. the Favites colony, on the right, with shared walls
The good news, however, is that precisely knowing the difference or getting it right all the time doesn’t matter materially, because the husbandry and aquarium care needs of each are substantially similar. So no need to worry if you see them incorrectly labeled at your local fish store and be kind if a fellow hobbyist confuses the two online. Caring for them is about the same.
Does it matter if you misidentify Favia and Favites?
For most aquarists, distinguishing between Favia and Favites is not critical, as their care requirements are nearly identical. However, there are a few scenarios where genus-level identification can be relevant:
- Aggression: Some aquarists report subtle differences in aggression between species and even between colonies, but both genera are considered aggressive and should be given ample space from neighbors.
- Growth Patterns: Favia may sometimes grow more slowly or develop more pronounced dome shapes, while Favites can spread more laterally, but these differences are often minor in home aquaria.
- Compatibility and Disease: If you notice unexpected aggression, rapid tissue loss, or unusual growth, knowing the genus may help when consulting with experienced hobbyists or troubleshooting rare issues.
In practice, if you’re unsure, treat any “brain coral” of this type as you would a Favia: provide space, monitor for aggression, and match care to the general guidelines in this article. Mislabeling is common in the hobby and rarely leads to major problems if you follow best practices for LPS corals.
Common misconception: Many aquarists worry that misidentification will lead to major care mistakes. In reality, the practical impact is minimal for most tanks. Focus on observing your coral’s behavior and health, and adjust care as needed rather than stressing over perfect identification.

Natural Habitat
Favia, like most reef invertebrates, can be naturally or originally found in warm, tropical reef waters around the world. This species is common in the Indo-Pacific ocean regions. Some locations where divers regularly see Favia Coral are Australia, Japan, and parts of Africa. Luckily, this species of coral hasn’t been greatly over-harvested and is still growing well in the ocean.
Look at how amazing this healthy old coral is
From reef to aquarium: In the wild, Favia corals are often found on reef slopes and lagoons, typically at moderate depths where light and flow are not extreme. They grow on rocky substrates and are exposed to gentle to moderate water movement. This natural environment explains their preference for moderate lighting and flow in aquariums, and their tolerance for a range of conditions. However, wild colonies may experience more stable water chemistry than is typical in new or unstable tanks, so strive for consistency when replicating their habitat at home.
Favia coral care
Caring for the Favia coral in a saltwater aquarium is a task that can be reasonably accommodated for beginner and advanced aquarium owners alike. They are generally hardy when provided their preferred aquarium conditions. Let’s dive a bit deeper into how to be successful with Favia coral care.
Water parameters essential to proper Favia coral care
Like most other aquarium corals, Favia corals need reef tank quality water parameters to be healthy and to grow in your tank.
- Alkalinity: kept stable, not fluctuating, but in between 8-12 dkh
- Ammonia, Nitrites, Nitrates, Phosphates: 0 parts per million, or as close as possible
- Calcium: 400+ parts per million
- pH: kept stable, but between 8.1-8.4
- Specific gravity: 1.025
- Temperature: kept stable, but between 73-84 Fahrenheit, 22.8 – 28.8 Celcius

These reef tank parameters are relatively easy to create, as long as you start out with a high-quality salt mix.

If you are having trouble creating and maintaining stable conditions as specified above and in the linked articles, it would be best to wait to add a Favia or any other coral species until that water chemistry and stability have been created.
Why are Favia corals sensitive to parameter stability?
Favia corals, like most LPS, rely on stable water chemistry for healthy calcification and tissue maintenance. Fluctuations in alkalinity, calcium, or pH can disrupt their ability to build skeleton and maintain tissue, leading to recession or stunted growth. Sudden changes in temperature or salinity can stress their symbiotic zooxanthellae, sometimes resulting in bleaching or tissue loss. Compared to some soft corals, Favia are less tolerant of swings, but they are generally more forgiving than many SPS corals.
Signs of parameter-related stress in Favia:
- Tissue recession, exposing white skeleton
- Loss of color or bleaching
- Polyp retraction or failure to extend
- Slowed or halted growth
Prioritizing interventions: If multiple parameters are out of range, address the most critical first:
- Ammonia and nitrite (should always be zero; toxic even at low levels)
- Temperature (rapid swings can be fatal)
- Salinity/specific gravity (stability is key)
- Alkalinity and calcium (for skeletal health)
- Nitrate and phosphate (chronic elevation can stress corals, but minor fluctuations are less urgent than above)
Avoid making large, rapid corrections—overcorrection can be as stressful as the original problem. Instead, stabilize gradually and monitor coral response. Consistency is more important than chasing exact numbers.
Tip: If you notice stress, check all parameters before taking action. Often, a slow, steady return to target ranges is the safest approach.
Favia coral placement
The best placement for a Favia coral is in a location that gets moderate water flow and moderate-intensity lighting. Too much flow may damage the polyps. Too much lighting will cause bleaching.
Placement trade-offs and diagnostic cues
Placement is critical for Favia health. Here’s how to interpret their response and adjust:
- Too much light: Favia may bleach (lose color), recede, or show tissue loss. Polyps may remain retracted during the day.
- Too little light: Coral may lose vibrancy, grow slowly, or show poor polyp extension, but is less likely to bleach.
- Too much flow: Polyps remain tightly retracted, tissue may tear, and feeding is suppressed.
- Too little flow: Detritus may accumulate, polyps may appear “suffocated,” and tissue recession can occur due to poor gas exchange.
Observe your Favia for a week or two after placement. Healthy Favia will show moderate polyp extension, vibrant color, and gradual growth. If you see signs of stress, adjust placement incrementally—move to a shadier or more sheltered spot, or increase/decrease flow as needed.
Adapting placement in mixed-reef tanks
In tanks with more demanding corals (e.g., SPS), Favia can be placed in lower or peripheral zones where light and flow are moderate. If your tank has variable lighting or microzones, use these areas to your advantage. In newer tanks or those with less mature biological filtration, err on the side of lower light and flow until stability improves.
Remember, Favia are aggressive and need space from neighbors. Their sweeper tentacles can reach several inches, so leave a buffer zone to prevent stinging or chemical warfare. Do not allow two Favia colonies to touch, as they will attack each other.
Lighting
Favia corals are photosynthetic, which means that they host symbiotic organisms, called zooxanthellae inside of their polyp tissues. Those zooxanthellae harness energy from the lights above the tank and use it (and carbon dioxide) to create sugar to feed themselves and the host coral. The sugar from photosynthesis is one of the primary sources of energy for the Favia coral. As such, ensuring the proper amount of light is a vital consideration to consider when planning your Favia Coral placement.
The good news though is that adequate lighting (sufficient to support the photosynthesis and majority of the nutritional needs) is on the lower side of moderate, by reef tank standards. As such, you can likely keep them successfully in the lower or fringe zones and keep the prime, more intense locations for more light-hungry species.
They share similar placement and care requirements with other popular LPS including: Scoly, Blastomussa, and Acan corals.
With that said, if you aren’t planning on filling the tank with some very light-hungry corals, they would likely benefit from more vs. less light. You just want to use caution and gradually acclimate them to more aggressive and intense lighting by either starting them in a darker location or dimming the lights and acclimating by gradually returning to your preferred intensity over a few weeks.
Distinct walls encircle each corallite in Favia corals
Water flow
Favia corals are large polyp stony corals and have similar water flow requirements as many of the other popular species in this category. They require low to moderate flow, which is to say, just enough of a turbulent or gyre flow that provides water circulation, without so much flow that you risk damaging the large, fleshy polyps. Too little flow and your coral may be slowly suffocating. Too much flow and you will suppress polyp extension and eating, or worse yet, tear the polyps and provide an opportunity for an infection. Just the right amount of flow and your coral will thank you and show off its best polyp extension.
Space
Another very important consideration of Favia coral placement is to ensure you leave sufficient room around the coral to prevent aggression between neighbors. Favia corals are infamously aggressive. They can form surprisingly long sweeper tentacles, which are specialized tentacles designed to sting, maim or even kill neighboring corals.
They may also literally try to dissolve or digest their rivals by releasing mesenterial filaments (bundles of digestive chemicals). They are generally not friendly neighbors.
Wow, that’s green! Give them lots of space or they will sting neighbors
Feeding
I generally say the same thing for almost every coral, with respect to feeding—so if you’ve read this before, please be patient. Because we worry about placement to ensure adequate lighting for photosynthesis, it can sometimes be confusing or feel contradictory to think of corals as animals, which is what they are. Remember, they don’t have the ability to photosynthesize on their own, they have symbiotic organisms inside them that feed them. But animals need to eat. And while you could potentially ‘get away without’ feeding your Favia corals, as long as they got the right quality of light, it’s not necessarily the best or right recommended approach.
Each corallite has feeding tentacles and a mouth…both apparatuses are designed…you guessed it…for feeding…for eating…for taking meaty foods, putting them in their mouths and digesting them. If you want to provide the best care for your Favia corals and want to see the fastest growth and best colors, I strongly recommend you feed them.
Consider feeding them at night, when their feeding polyps are extended, by turning off the pumps and directing the food into the polyps/mouths with a Sea Squirt or Julian’s Thing. They will accept small meaty morsels, like pieces of brine shrimp or mysis shrimp (if your fish leave them alone), and also would likely accept prepared foods, like Reef Roids or small pellets. Leave the pumps off for 30-minutes to an hour and set a timer to remind yourself to turn them back on, or use a smart plug to program it, so you don’t forget.
Feeding, growth, and water quality: finding the balance
Feeding Favia corals can accelerate growth and enhance coloration, but it comes with trade-offs. Excess food can lead to nutrient spikes (elevated nitrate and phosphate), which may fuel algae growth or stress sensitive tank inhabitants. Overfeeding is a common cause of declining water quality in reef tanks.
- Frequency: Feeding 1–3 times per week is usually sufficient for optimal health and growth. More frequent feeding may not yield better results and increases nutrient risk.
- Food types: Small meaty foods (mysis, brine shrimp, specialized coral foods) are best. Avoid large chunks that can rot or be ignored.
- Water quality management: Use protein skimming, regular water changes, and/or refugia to export excess nutrients. Monitor nitrate and phosphate levels, especially after changes in feeding routine.
- Practical tip: Target feed with pumps off to minimize waste. Observe your coral’s feeding response and adjust quantity as needed.
Common misconception: Some believe photosynthesis alone is always sufficient for LPS corals. While Favia can survive on light alone, supplemental feeding produces noticeably better growth and color in most tanks.
Do you have to feed Favia corals?
Feeding Favia corals is not required, but it is recommended, for optimal health and growth.
Growth
Favia corals generally start out as a small frag that has from one to a few corallites on it, but given enough time and the right aquarium conditions, they will grow up to be a large, mound-shaped stony coral.
How fast do Favia grow?
Favia are a slow-growing coral. If you feed them a few times a week, you may see a few polyps/heads added in a year, and less if you do not feed.
What influences Favia growth rate?
Several factors affect how quickly your Favia will grow:
- Lighting: Moderate, stable lighting supports healthy growth.
- Feeding: Regular feeding accelerates polyp addition and skeletal expansion.
- Water chemistry: Stable alkalinity, calcium, and magnesium are essential for calcification.
- Competition and aggression: Nearby aggressive corals or chemical warfare can suppress growth.
- Tank maturity: More mature tanks with stable parameters generally support better growth.
Benchmarks: Under optimal conditions, expect 1–3 new polyps per year from a small frag. Stalled growth may indicate parameter instability, hidden aggression, or insufficient nutrition. If your Favia isn’t growing, review placement, check for aggression, and confirm water quality is stable.
Reproduction & Propagation
Like other corals, the Favia can reproduce both sexually and asexually, but sexual reproduction is extremely rare in the home reef aquarium. Asexual reproduction, through fragging, is much more common. Because each Favia coral colony is stony and mound-shaped, it can be a bit intimidating to think about fragging them, because the process involves cutting into them with a tile saw or Dremel-style rotary tool.

Disease, dying, and troubleshooting
Sick, dying, or diseased Faviids may first show stress through receding polyp tissue. Rather than being thick, colorful, and inflated, stressed, or dying Favia coral tissue will recede, showing some of the aforementioned skeletal walls that define their genus.
Diagnosing Favia health issues: checklist and causes
- Tissue recession: Often caused by parameter instability, aggression from neighbors, or poor flow. Look for exposed white skeleton and receding tissue margins.
- Brown jelly disease: Appears as a brown, slimy mass on the coral. Usually follows physical damage or parameter swings. Highly contagious—remove affected tissue and improve water quality.
- Bleaching: Loss of color, often due to excessive light, temperature spikes, or salinity swings. Move to lower light and stabilize parameters.
- Polyp bailout: Polyps detach from the skeleton, typically a last-ditch survival response to severe stress (chemical, physical, or parameter-related).
Preventive strategies and early interventions:
- Maintain stable water parameters and avoid rapid corrections.
- Provide adequate space to prevent aggression and allelopathy.
- Ensure moderate, non-laminar flow to prevent detritus buildup and promote tissue health.
- Quarantine new corals and consider coral dips to reduce pathogen introduction.
- At first sign of tissue loss or brown jelly, isolate the coral if possible, remove affected tissue, and increase flow around the remaining healthy polyps.
When to consider drastic measures: If infection or tissue loss is spreading rapidly and other interventions fail, fragging healthy sections away from diseased tissue may save part of the colony.
Cost and availability
Favia is a popular species of coral that can easily be found in shops around the world. They are easy to take care of, so any store that offers reef fish will likely have some specimens for sale. Their relative abundance and ease of care also align nicely with the fact that they are generally reasonably priced, as well.
