Whats going on with my zoas?

Having an issue with this colony recently. Looks like they are stretching for light or irritated. All other colonies are short and flat polyps something is going on with these. Let me know what you think. Thanks.

I've switched over to all for reef for dosing but they were doing that before the switch. No other changes or additions.
