Hi reefers I bought a Purple Gorgonian about 6wks ago. The polyps were totally white which is what attracted me to it. Great contrast right Well now that it's been in my tank for these 6wks all the polyps have turned brown. Not a good contrast It appears healthy. All polyps fully extended, not an empty spot from top to bottom. I've see pictures where these gorgs polyps are brown. I'm feeding it Coral Extacy which is a zooplankton. Are they supposed to be brown or white?
