Yellow Polyp

General information

In general, corals coming from the genus Parazoanthus have long tentacles that is attached to a fluted body. Instead of looking like an encrusting mat, the polyps from this genus are individually spaced and attached. Taking a closer look at their polyps, you will observe that they simultaneously doing an Open and Close motion which is believed to be a sort of chemical communication.   
As for the Yellow Polyp, they are predominatly colored yellow in its tentacles and white in its stalk. This are the water parameters for cultivating Yellow Finger Gorgonian:

Calcium: 420 – 440 ppm
Alkalinity: 2.86 – 4.259 MEQ/L (8 – 12 dKH)
Phosphates: > 0.10 mg/L
Magnesium: 1260 – 1350
Strontium: 8 -10 mg/L
Temperature: 72° – 78° F (22° – 26° C)
Salinity / Specific Gravity: 1.023 – 1.025
pH: 8.1 – 8.4

The Yellow Polyp is not a photosynthetic species. They get their nourishment by snatching small foods present in the water like plankton. Supplemental feeding is highly advised where you can give them brine shrimp and mysis.

The Yellow Polyp should be placed at the bottom portion of the tank. You may need a gel glue or putty to fasten them on an exposed rock.

The Yellow Polyp only requires minimal lighting but a strong flow of water. This is the reason why they should be placed at the bottom of the tank.

The Yellow Polyp are a subtropical species found in the Western Atlantic Ocean, particularly in the USA and Canada.

While the Yellow Polyp is not aggressive, you still need to give ample space between other species corals. What you should be cautious is during the handling process since the branches are highly brittle and can easily break off.

Yellow Polyp are purely marine species. Therefore, salinity must be entirely maintained from 1.023 to 1.025 specific gravity.
