Weeping willow toadstool polyp extension question.

[Kimberely]

I've never gotten the super long polyp extension on my weeping willow toadstool that it had in the holding tank at my local reef shop. Otherwise it seems healthy and has trippled in size since last spring. Can anyone tell me how to get full polyp extension on this guy? Is it a lighting issue? Flow?

I don't have experience with it. Try playing with light settings and flow.
