Zoanthids acting funny

[Spilo26]

Some zoas in my tank are growing really tall and skinny after awhile, what would cause this? I have a BC 14 with a 70 watt metal halide over it, and all water parameters test fine. Im at a loss, could my iodine be low?

Is it possible they are palys that are opening for the first time?

I'm with Friday Night on the lighting as well. Is there a film buildup on the surface of the water? How clear is the water? Do you run carbon?
