Sure it would depend on what lighting, K value and many other factors. You may need to play with them a bit. Start them at mid range and go from them keeping an eye on them. PEs tend to morph quite a bit and depending on what you are looking for will depend on where you end up keeping them.
But all in all, the type of lighting and K value and even flow will play a big role in where they do best.
That is all part of the fun in keeping zoanthids, learning where they do best in your tank.
