Notice the difference in the edges?

Could be because of lighting and water flow.
How much of each do you have?

I think I have enough of each. Tek T5 6 lamps and 1200 Mag return w/ Korallia 3 and mp20. This change came during the time where I had a nail rusting in my reef that had a negative impact on my corals during the same time it was rusting.

I'm having the same problem with some zoas that have been in my tank for a few months. Tagging along in hopes of some answers.
Free bump!

It looks like the tentacles are longer, correct? Common observation is that with zoanthid type polyps' tentacles will grow/shrink according to flow and possibly light conditions. In my own tank, I've noticed that the palys' tentacles are longest when they are in the most flow.

Definitely the lighting. That's one of the cool things about zoa's, you can morph them with different light. You either have stronger or less light than before. I am guessing you have stronger lights than where they came from.

Where they came from had MH lighting. And yes, the tentacles are longer and more "disorganized" looking.

I seem to experience the same thing. Lighting only seems to effect the stalk length, not the tentacles.

Flow

Why do you think?

I had that too. My zoas that where next to the surface (near lamps) had longer tentacles, the ones in botton, not. They had the same flow.
I believe they like less light, so they try to cover themselves with tentacles.

Zoanthids grow on rocks that are out of the water on high tide. They like high light. It is the flow...
