Do my BTAs want more light?

With the new anemone tank, I'm slowly trying to figure our how much light these guys want.

17 gal tank. I have a singel Kessil A360W about 8" over the water, and they sit about 6" or so under the water as such -

In this picture, the lights slowly ramp to 30% at peak, then back down during a 12 hour lighting cycle. They look fat and happy, but i can't tell if they want more light as they almost appear to be stretching -

Noticing this, I've started to increase the lighting intensity by about 5% per day for the last two weeks. Zero change until i hit about 60% on the light intensity, they two of the smaller ones started to move around - but they moved to an area of higher light! The big ones remain as stretched as before.

I continued to increase the light until I hit 80% with no change in anemone behavior. It seems like the clowns hide in the nems during the peak time, maybe it's too bright for them? So I went back to 50% where everything seemed cool and am now asking the question.

I don't want to hurt anything, so should I keep increasing the lighting? Or do these BTAs look happy?
