Ruffled Palys...why?

[Myka]

The one unIDed Paly is in shade. The Nuclear Green was in the brightest part of the tank, but it fell down onto the sand a few weeks ago, and there it remains. I'm mad at it because it is ruffled. I can't really put them in less light. I could try diffusing the light for awhile with some screening, and see if there is a difference. I will try adding carbon for a week first, then try diffusing the light. That way, if I notice a change I will know what caused it. I would think that if it was due to lighting intensity that there would have been a change when I messed around with bulbs which should have had about a 35% difference in PAR.
