My Zoas are acting weird

[BellaCoop]

My zoas have been hiding and only a few come out. Iv tried to change the lighting I am currently using the BRS reef lighting set up on my HD Primes. Any advice on what I can do to make them open up again?

Turn the UV down, check for the usual suspects like Nudibranch, Spiders, Sun Dials, Asterina.
