The ORA Aquacultured Grube's Gorgonian, Pinnigorgia flava is a fast growing gorgonian coral that is a graceful, thin-branched that can be described as tan to pink in color with similarly colored polyps. It is pinnately branched, forming tall, feather-like colonies and has a beautiful coloration. ORA obtained this coral about 3 years ago from Julian Sprung. It has an extensive history in the Aquarium Hobby which Julian was glad to share with us. Originally collected in the Philippines around 1990 by Klaus and Rosalia Grube. Julian named it after Klaus and Rosalia Grube. Named Grubes Gorgonian, pronounced Grooba’s Gorgonian.
Difficulty
The ORA Aquacultured Grube's Gorgonian is good for a dedicated beginner, its fairly hardy, as long as it is fed and the water is kept clean and stable. They are easier than many photosynthetic gorgonians.
Aggressiveness Very peaceful, poses no threat to any other corals or gorgonians. However, other gorgonians can over take it, so they will need to be kept at a distance. Adequate space should be provided between them and other corals that can extend sweeper tentacles as well.
Waterflow
Requires a moderate level of water flow.
Lighting
They will do well on any reef lighting from Low to High. It has been shown that lighting that has 350 to 550 nm , which is the blue phase, is the most beneficial.
Placement
Place anywhere which provides the required water flow and lighting level.
Diet and Feeding
An Omnivore - The Pacific Pinnigorgia Gorgonian in the wild captures planktonic organisms and microscopic food particles from the water column, and can absorb dissolved organic matter. Unlike a lot of other Gorgonians, the Pacific Pinnigorgia Gorgonian has a symbiotic relationship with a marine algae known as zooxanthellae, where they receive a portion of their nutrients from.
In captivity, the Pacific Pinnigorgia Gorgonian can be fed enriched Artemia nauplii, rotifers, dust-sized pellet food, copepods, daphnia, and other similar sized foods. Marine Snow is also a good food source. Stirring the substrate to suspend edible particulates is helpful, along with the presence of fish which can also help nourish it. Feed every other day depending on appearance.
