So I should sell those and the aquatic life LEDs and buy a value fixture
how long has the zoas been in your system? Do you see the body of the zoas stretching out further? That's usually indication that it needs more light.
The partially closed habits can be a light issue or also and irritation issue. when i had zoa eating nudibranch and micro nudis (size of a sand grain), my zoa's skirt would do that. I've woken up in the early mornings often where there is light some ambient light from the eminent sunrise and notice my zoas and palys fully open, inflated and extended.
back to light, hexagon tanks are fairly deep. Sounds like your 3 LED strips that I assuming is not using optics so depth penetration might be insufficient. Upgrading to a concentrated LED panel type light will help better light penetration, especially since the bargain ones don't normally have optics.
