Zoas and paly?

[HUNTER1]

My zoas and plays are always look like these but other corals are fine, maybe too much lighting? I have 4x39 ATI bulbs over a 40g. These corals are about 20 inches from the bulbs. They're attached to the rocks and can't move them, any idea? thanks

More likely a parasite than too much light.

Iyt could very well be rtoo long of a photperiod... Are you running the lights much more than 8 hours? If so, cut back to closer to 8. Also, be very careful with those protopalythoa, they're evil little weeds that will take over a tank if you don't keep an eye on them.

I run my blue for 12 hours and whites for 8 hours. I have other palys that are doing ok. Ill see if I can move the zoa..I know they spread fast.

Did you acclimate them to the lighting or just placed them where they currently reside?
I used to run my T5s Blue's 9-10 hrs and other colors 6-8hrs.

They were fine before with these llights and placements and just stopped opening.

Strange usually they are very hardy, nothing fell on them that could have hurt them?

thoes palys look fine.. hard to tell by the pics but im guessing they are starting to irritate the zoas.. paly take over time

what are your water parameters

+1 on cutting down a little on lighting time, or you can raise the light a little higher from the tank.
