Wondering if there is any general negative to putting Birdsnest coral next to zoanthids? I have no other place to put the Birdsnest if that comes to mind as a suggestion.
Yea some zoanthids will grow into the birdsnest corals which could become a problem. A lot of the nice zoos that come in are actually collected from areas where they grow on dead birdsnest skeletons.
Just give them some time and keep a close eye on them. Im sure there is some place you can put the BN frag, therenis almost always a spot. When I run out of room on the topmof my rock I start glueing frags to the sides or even on top of other corals like monti caps.
