Palys crawling away, ruffled edges.

Had a couple questions to see if anyone has any input.

In one system, I placed a frag of palys which were tightly packed onto a rock. They are all crawling off the plug in opposite directions, so now there are single palys migrating away from the center of the rock where the disc was placed. My first assumption is that they are receiving too much light, does this sound plausible? 400 w Radium, 16" from water, palys about 8" under the water.

Second question, whem moving grandis from a lower flow lower light frag tank to a different system, they now have "ruffled edges" instead of being flat like a dinner plate. My first assumption in this case is that high flow will cause them to ruffle up, but maybe it's from getting more light?

I guess in my mind I have assumptions to why this is happening, but I wanted to see if anyone else has first hand experience. The palys all still look great-- i'm just curiuos as to what influences their behavior to get a better understanding.

my grandis when I had my collection before always stayed on the sand bend or lowest rock formation, they never liked too much light.

Even the the ones I have right now are in the back rock work near the bottom, the ones I have right now resemble these. ( not my pic )

I love keeping grandis in high light and flow. They stay smaller and have much more white marbled pattern to them. Add some blue LEDs to it and they are awesome polyps!

Thanks for the input guys. After giving them a couple weeks under the more intense light, the polyps are a little smaller, the edges are ruffled, and there is a lot of white speckling/patterns coming through as mentioned. They look cool though!
