Need Help! Magician Zoa looks bad

[Labmaster]

Hi,

within three days my Magician Zoas look realy bad.
First they looked swollen and the mouth was wide open. Now they look as if shortening the tentacle.
Other Zoas in the Tank looks good.
Have someone a idea what was happened?

My Parameter:

Temp 26°C
KH 7,5
NO3 10
PO4 0,01 (set to 0,03)
Ca 420
Mg 1800 (because treatment with Marine Tech M against bryopsis) since 4 weeks

greetings

Christian

What type of lighting do you have? As well as what type did they come from?

i have a ATI Hybrid with 4x54W T5 and 3x 75W LED.
The Zoas is already for month in the tank

Ah, any sudden change in parameters? I have noticed mine do this before at one point. Then 2-3 days later, back to like nothing had happened. Not 100% sure since not a new acclimation however. Hope someone can chime in with a more definite response.

i looked at my notes about water parameters. There i found some jumps in KH:
17.06. KH 7,5
18.06 KH 8,5
19.06. KH 9,0
22.06. KH 7,9
maby this is the reason...but why only the Magician?

No real answers here, but some insight may be there. I'd be speculating at this point and hope someone comes with a definitive answer to help out.
I do know there are many a different types of zoanthids so different reactions isn't unheard of.

thanks for the link....who you say, no real answers.
But it is interesting that it is also the magician.

Two zoa/palys that hate my tank, magicians and pink kraks. No idea why but they used to do awesome now they just either melt away or don't grow at all. Hawaiin palys also hate my tank.
