  •  pH: 8.1-8.24

Ensuring that the ammonia, nitrite, and nitrate levels are undetectable or kept as low as possible is essential. Regular testing of water parameters is crucial, and appropriate adjustments should be made to maintain optimal conditions.

Lighting Recommendation

For optimal growth and health, trumpet corals require low to moderate-intensity lighting. It is recommended to use a quality reef lighting system that includes a combination of blue (actinic) and white spectrum lights. Ensure that you adjust the lighting intensity based on the specific needs of your trumpet corals to prevent any adverse effects.


Maintaining good water quality in an aquarium is critical, and a well-functioning filtration system is essential to achieving this. It is advisable to utilize a combination of filtration methods, such as mechanical, biological, and chemical filtration, which may include a protein skimmer, live rock, and activated carbon.

Substrate and Rockwork

To create a natural-looking environment, it is recommended to use a fine-grade substrate like aragonite sand or crushed coral. Arrange live rock within the tank to provide secure anchors for trumpet corals and offer hiding places for the inhabitants.

Water Flow

Trumpet corals thrive best in moderate water flow that emulates their natural habitat. Employ powerheads or wavemakers to create gentle water movement throughout the aquarium to achieve this. It is essential to prevent the accumulation of detritus by ensuring that there are no dead spots.

It would be best to position the trumpet corals in a part of the aquarium that receives appropriate lighting and water flow. Keep them away from aggressive corals or fish that may cause harm or irritation to them.


Consistent upkeep is essential for sustaining a thriving trumpet coral tank. Regularly perform water changes to sustain stable water conditions and eliminate accumulated debris. Stay alert for signs of stress, disease, or coral aggression, and take appropriate measures.

Diet & Feeding Guide of Trumpet Coral Fish

Trumpet corals predominantly rely on photosynthesis and derive a substantial portion of their nutrients from the symbiotic association with zooxanthellae algae residing within their tissues. However, supplementary feeding can also support their growth and intensify their pigmentation. The following are some recommended feeding practices for trumpet corals:


Maintaining appropriate lighting conditions is essential for the health and nutrition of trumpet corals. As they rely on photosynthesis as their primary energy source, it is important to use a reef lighting system that includes blue (actinic) and white spectrum lights to support their photosynthetic needs.


To ensure optimal photosynthesis in your trumpet corals, it is essential to provide sufficient light intensity by placing them in a suitable tank area. The specific lighting requirements vary depending on the coral species, and it is important to determine the optimal placement accordingly.

Target Feeding

Trumpet corals have the ability to derive nutrients from their surrounding water. However, they can also capture and consume small food particles. Target feeding can be facilitated by using a specialized coral feeder or a turkey baster to deliver small meaty foods directly to the polyps of the trumpet corals.

Appropriate Diet

Trumpet corals are known to consume various small meaty foods with ease. Some suitable options include:

  • Brine shrimp
  • Mysis shrimp
  • Cyclops
  • Chopped seafood such as shrimp, fish, and clam
  • Commercial coral foods, specially formulated for filter-feeding corals.

Feeding Frequency

It is optional to feed trumpet corals on a daily basis; however, offering supplemental feedings once or twice a week can enhance their growth and overall health. Monitoring their response and adjusting the feeding frequency based on their appetite and growth rate is recommended.


During each feeding session, it is recommended to provide small amounts of food to trumpet corals. Overfeeding can lead to water quality issues and can harm the corals. To avoid this, observe the amount of food the coral consumes within a few minutes and adjust the quantity accordingly.

Common Diseases in Trumpet Corals & Their Treatments

Trumpet corals may be vulnerable to certain illnesses like any other living organism. It’s crucial to closely observe their health and take the necessary actions if any disease indications appear. Here are some typical illnesses that can impact trumpet corals and potential remedies:

White Band Disease

White Band Disease is characterized by the progressive appearance of a white band on coral tissue, which gradually moves from the base toward the polyps. This process leads to the exposure of the coral skeleton.

To prevent the spread of White Band Disease, it is necessary to quarantine the affected coral in a separate tank. The infected tissue should be gently removed by means of a sterile tool, cutting carefully below the advancing white band.

Coral-safe antibiotics or dips designed explicitly for bacterial infections should be applied, following the manufacturer’s instructions.

Black Band Disease

Black Band Disease is characterized by the appearance of a dark band that gradually spreads across coral tissue, leaving behind a bare skeleton. In some cases, a white or brown border may also be observed. An unpleasant sulfurous odor may be detected in the affected area.

To prevent the spread of the disease, it is essential to isolate the affected coral in a separate tank. Infected tissue must be removed gently by cutting below the advancing black band with a sterile tool.

It is crucial to use coral-safe antibiotic treatments or dips specifically designed to treat bacterial infections and to follow the manufacturer’s instructions.

White Plague Disease

White Plague Disease manifests through rapid tissue loss, leading to a spreading white lesion on the coral. The lesion may have a distinct border, and the coral’s polyps may recede or disappear.

To prevent the spread of the disease, it is advisable to quarantine the affected coral in a separate tank. Additionally, it is recommended that infected tissue is gently removed through careful cutting below the advancing lesion using a sterile tool.

Coral-safe antibiotic treatments or dips designed explicitly for bacterial infections should be applied, following the manufacturer’s instructions. 

Water quality should be improved, and stable parameters maintained to support the coral’s recovery. Furthermore, optimal lighting, water flow, and nutrition should be provided to enhance

Suitable Tank Mates for Trumpet Coral

When selecting tank mates for this species, it is vital to consider their needs and size. Trumpet Coral is a large polyp stony (LPS) coral and requires ample water flow and stable water parameters. 

Avoid keeping too many aggressive fish or invertebrates in the same tank, as they may harass or nip at the coral’s delicate tissue. SPS corals are an ideal addition for a tank with Trumpet Coral, as their sweeper tentacles generally aren’t long enough to cause harm to other tankmates. 

Varieties such as Bird’s Nest Coral (Seriatopora hystrix) and Green Bali Slimer (Acropora yongei) are ideal for beginners. Remember that SPS corals need a lot of currents and light, so ensure they’re placed according to the Trumpet Coral.

Soft Corals are also a great choice with Trumpet corals; however, they can overgrow and require regular trimming to prevent them from overgrowing other corals. Low-light corals are great tank mates for reef-safe fish like Clownfish, Yellowtail Blue Damsels, Tangs, Blennies, Gobies, Firefish, Basslets, Grammas, and many others. 

However, caution should be taken when housing Pygmy Angelfish due to their marine grazing habits which could lead to them eating Trumpet Corals and other polyps if they do not have sufficient macroalgae. 

As for other invertebrates, Trumpet Corals are safe to keep with any shrimp, crabs, and snails that are not too large and will not bother them, with the exception of Peppermint Shrimp.
