I keep them in very low lighting at first. After a week or so I up the lighting from just PC's to PC's with 175w halides. I keep them towards the bottom of the tank.
I've been experimenting with one morph. I have a piece of it under a ledge in the tank described above, and a piece under a single 400w halide, 10" from the surface.
Both pieces are surviving, but there color is changing. I can't tell which one I like more. The piece in the dark has kept it's pink ring, but the center looks pale. The piece in the bright tank still has some pink ring, but the center has turned a baby blue. Also, the outer parts of the polyp look darker.
I'll try to get some pics of the two pieces.
