Zoas change colors

[Oohkris123]

A few months ago I bought a frag of blow pops bright blue and red or orange mouth. It's closed and stayed retracted for almost 2 weeks and now it's starting to open back up and it's a super bright green with a red mouth.. what happened?

when they were blue

now they're green...

the rest of my zoas look completely fine

Due to them closed up for a while they missed the light and when corals don't get enough light the turn green, yes zoa's as well.
If the open back up as they are they should color back up.
Of course many wild zoa's can morphing into a different color.

I like the green I really don't mine the green I thinks it pretty cool they can change color... I'm just worried that it would have died or some

Can this happen due underlighting as well? Even when they are always open? i have a few frags sitting next to each other at circa 75 PAR, and one frag looks green like this. I have always wondered why it was like this.

Yes, possible.
Nutrients are playing a roll as well.
I have seen $100 per polyp zoa's turn into $1 zoa's, they just morph and there's nothing you can do.

I wonder if the type of light male them change mine are under LED

The spectrum is something i can't dial in, intensity aswell.
Right now i'm slowly rising blue's up and leaving the whites at the same percentage.
But what is enough and what is the right spectrum? So hard to find for me.
