just give it time, stable parameters, and good light. also good parameters. thats pretty much how everything works in this hobby
Some of mine grow like crazy anywhere in my tank, while others have to be moved several times just to get them to open, yet alone grow.
Great info. Most people have good growth with fragging to entice new growth, proper lighting, mild/moderate flow, feeding the proper food and stability. I know these things work for me. If you are looking for good food try Rods, Reef-Roids, and Coral Frenzy. They really made a difference in my tank.
