Too much?

I moved my rics/zoa into a 40b over the weekend. I felt that the 400w mh was too much even in the larger tank. I noticed that some of my lighter colored rics were shrinking over the last few months.

I set the new tank with 2 x 39w T5 (10k) and 110w PC Actinic. Should this be ok? I haven't seen them expanding too much like they used to, but it has only been a few days.
