green star polyps not out Two days ago i noticed that my green star polyps didnt come out. All of the other corals are fine.(xenia, leather toadstool, other polyps, featherduster) The green star polyps have been in the tank longer than any of the others and have never shown a sign of "not opening" There is no debrit on the matt, and there isnt any coral doscoloration or any signs of stress. The water param were checked just this morning and and are no more usual than any other day. What in the world happened? On a side note, i bought a baby cleaner shrimp (2" long). My engineering goby ( the one with a reputation for killing things (in other threads) killed him.
