About Black Hole Sun Acan
General information
You also have to look out for other factors and must stay within the range:
- 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, Black Hole Sun 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 Black Hole Sun Acan. Water must be change either 20% per month or 5% weekly. Thriving them with fish is recommended as fish excretes nitrogen that can sustain the coral's growth.
Breeding & spawning
Black Hole Sun Acan does not need high flow rate and intense light. Giving them moderate lighting allows the Black Hole Sun Acan to spread their polyps thereby allowing them to feed. Too much light will cause the polyps to be retracted.
Cautions
Except for their own kind, Black Hole Sun 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
Black Hole Sun Acan are purely marine. So, therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
