I'm not sure if they will attatch.. I raise stuff like that in a seperate aquarium with no shrimp or fish where I can put them somewhere and watch them without molestation.
my favia is getting ready to drop around 5 or 6 babies. how do people attach them to a rock. since they are so small i don't want to use superglue. can i just set them on rock in a low current part of the tank so they can atach themselves? I am worried about shrimp etc picking at them and then who knows where they will go.
