ECO-GORGONIAN ™ are sustainably produced Caribbean photosynthetic gorgonians. Small frags are sustainably collected in the Caribbean and then are attached to coral plugs & grown in a Florida greenhouse until encrusted and ready for the home aquarium. The adult colony is in no way affected and regrows its branches creating a no impact sustainably collected gorgonian for your saltwater reef tank.The Purple Blade Eco-Gorg™ is a beautiful and hardy gorgonian that is found living in shallow sunlight flats of the Florida Keys and throughout the Caribbean. In the aquarium, it shouldn't be allowed to come into contact with other gorgonians, corals, or anemones to minimize inter-species aggression. Purple Blades prefer at least medium variety of lighting, but should have decent water flow, as they need it to occasionally shed a waxy film (much like a Sarcophyton sp. toadstool leather coral). The Purple Blade Eco-Gorg™ has a unique growth form unlike other photosynthetic gorgonians. Only the edges of the blades sport small polyps, allowing the purple color to be seen at all times.
