I have one of these dendro's (pic is just a general pic, not mine)...but looks like mine....I have a large single polyp...one that has budded on the left side adn what looks to be like a newly forming bud on the right side....I just noticed that it's tenticles are all pulled in and it is spitting out a white cloud like substance....looks just like oyster feast, actually......should I be concerned?...doesn't seem to be making the zoas or other corals nearby close or react
any help would be appreciated
