About Fat Head Acan
General information
Fat Head Acan have columnar that are well pronounced where you can see a bulging mound in each corallite.
This is the ideal range of water parameters for raising Fat Head Acan in captivity:
- Calcium: 400 – 450 ppm
- Alkalinity: 3.2 – 4.8 MEQ/L
- Phosphates: 0
- Magnesium: 1200 – 1350
- Strontium: 8 – 10
- Temperature: 76° – 83° F (24° – 28° C)
- Salinity / Specific Gravity: 1.023 – 1.025
Diet & nutrition
In the wild, Fat Head Acan has developed a symbiotic feeding relationship with marine algae called zooxanthellae. But in captivity, you have to feed them with nanoplankton or dissolved organics.
Determining sex
A mature tank is highly recommended in propagating Fat Head Acan. Thriving them with fish is recommended as fish excretes nitrogen that can sustain the coral's growth.
Breeding & spawning
Fat Head Acan does not need a high flow rate and intense light. Giving them moderate lighting allows the Fat Head Acan to spread their polyps thereby allowing them to feed. Too much light will cause the polyps to be retracted.
Cautions
Except for their kind, Fat Head Acan is aggressive towards other species. During the night, they extend their tentacles and sting nearby corals. It is recommended to observe proper spacing between corals. Further, they have the tendency to be overpowered with soft corals and will die especially if soft corals outnumber them.
Acclimation process
Fat Head Acan are purely marine. So, therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
