I have some button polyps in my tank, brown, green, and orange, and they have not been opening fully. There tentacles will not come out. Tests are all good and the rest of my critters in the reef tank are looking normal. Any ideas???? Thanks!
I had the same problem and what I did was move them around the tank untill they were happy.So it was either to much light or not enough current becuase they are now mid level and in mid current.
