General Information About Duncan Coral

duncan coral basic information

Duncan Coral (Duncanopsammia axifuga) is a popular large polyp stony (LPS) coral species native to Australia and the South China Sea. It is renowned for its relaxed care routine, fast growth rate, and ability to thrive in saltwater aquariums.

This coral species exhibits unique color variations, with roundish, disc-shaped bodies and large, portly tentacles that come in various colors. When disturbed, Duncan Coral can retract its tentacles for protection. It can grow in branching or clustered forms, making it an aesthetically appealing addition to any saltwater aquarium.

Duncan Coral requires an optimal care routine, including specific tank requirements such as a tank size of approximately 15 gallons, moderate lighting, gentle water flow, and regular water changes to maintain water quality.

Tank and Water Requirements for Duncan Coral

Tank and water requirements play a crucial role in the successful care and maintenance of Duncan Coral in saltwater aquariums. Duncan Corals are suitable for aquarists of all skill levels and require a tank size of approximately 15 gallons.

Water quality is essential, with temperature and pH levels ranging from 75 to 80°F and 8.0 to 8.4, respectively. Duncans prefer gentle or low water flow to aid in feeding, and regular water changes are necessary to maintain water quality and trace elements. It is important to note that Duncan Corals do not do well in moderate to heavy water flow as it can cause their polyps to retract.

Floating prey should be allowed to drift near their tentacles for feeding. Overall, providing the appropriate tank and water conditions ensures the health and well-being of Duncan Coral, promoting their growth rate and feeding habits.

Lighting and Substrates for Duncan Coral

Lighting and substrate play crucial roles in creating optimal conditions for the growth and well-being of Duncan Coral in saltwater aquariums. Here are some important considerations for lighting and substrates:

  • Best lighting options: Duncan Corals require medium lighting for continued growth. High lighting can stress the corals, so direct lights like metal halides should be avoided. T5s or LEDs with 70 to 100 PAR are suitable for Duncan Coral lighting. Different light settings can result in varied colors for the corals. Placement of Duncan Corals should be near the lighting but not in the dead center of the tank.
  • Advantages of sand substrates: It is not recommended to place Duncans directly on a sand substrate as it can irritate them. However, sand substrates are preferred for the coral to adjust and thrive. Duncans may not be as colorful as other options, but they are fascinating to observe under the right light and substrate.

Fertilizers and Propagation of Duncan Coral

Fertilizers play a vital role in promoting the growth and overall health of Duncan Coral in saltwater aquariums. To ensure their continued growth, it is important to maintain proper calcium and magnesium levels.

Duncan Corals require calcium levels between 400-460 ppm for optimal growth, which contributes to polyp formations and overall health. Aquarists can start with 400 ppm and adjust accordingly.

Additionally, corals can be propagated through fragging, which involves cutting a segment from the mother colony to establish a new colony. Fragging Duncan Coral allows for the creation of multiple new heads from a single polyp in just one month.

It is essential to perform fragging gently and with the appropriate tools, such as an electric bandsaw.

Proper fertilization and propagation techniques contribute to the vitality and success of Duncan Coral in saltwater aquariums.

Tank Mates, Feeding, and Health of Duncan Coral

Duncan Coral, a popular species of LPS coral in saltwater aquariums, can thrive when kept with compatible tank mates, provided with proper feeding, and maintained in optimal health conditions.

Tank mate compatibility: Good tank mates for Duncan Coral include clownfish, wrasses, tangs, and cardinals. Invertebrates like shrimps should be avoided as they may harm the coral. It is also important to keep harmless corals away from aggressive or defensive ones.

Feeding schedule for Duncan Coral: Duncans can survive without additional feeding as they get most of their sustenance from symbiont algae. However, feeding can help accelerate growth. Suitable food includes nauplii larvae, brine shrimp, copepods, and mysis. Target feeding with a baster is recommended to avoid overfeeding and contamination.

Maintaining optimal health: Regular water changes and proper water parameters are essential to prevent most health issues. Symptoms to avoid include discoloration, slime-coating, ragged-looking tentacles, and retracted polyps. A top-notch filtration system and protein skimmer can help clear out contamination from feeding.
