I originally purchased this sunny d frag about 6 months ago. I bought it with 3 heads, and it now has about 12. This is good, but growth has stalled and the polyps are not fully opening, for the last couple of weeks. My other zoos, palys and misc. softies/lps are doing fine. I removed a couple worms with hard tubes from the frag, and cleaned off debris with a powerhead. They are still not looking great/fully opening. Any suggestions?...do these generally like higher or lower par? Again, I have about 30 other frags of softies and lps, no issues. They are under LEDs.
