My clove polyps took about 2+ weeks to "come around". Of course during that time I was moving them around to find the rght "spot", more for me than for the colony. When I finally just left them be, they really took off. Maybe it is just "the right spot", quite by accident I'm sure. At any rate, now, into their 4th week as my tank residents, (and now my favorite, just beautiful),  they have at least 13 new polyp "babies". They really took off!
They are in the top 1/3 of the tank, under PC (64watt), and close to a Maxijet 600 with a Hydor so they get nicely but not unduly blasted every 15-20 seconds or so.
That's my story. They sure are happy campers now, but it took them awhile. Be patient.
