Zoas not opening

[40g Nano]

I have a 14 biocube and some Palys and zoas are not opening. Please help me find out why

 

[Fred2482]

Could you share your parameters?

 

[40g Nano]

Other corals r doing good and zoas right next to it are good to

what specific parameters

 

[Fred2482]

What about pests? Have you dipped them?

 

[40g Nano]

No

All parameters will help and are they new additions to the tank ?

 

[Fred2482]

So its hard to say with limited information. I would be curious on flow, par, all parameters....... However if everything else is doing great, I would inspect for pests. There are many pests that go after zoas...

No2-0 No3 less than 5 calcium 420 ph - 8.1

A little more than a week

 

[Fred2482]

How long has the tank been up? Where the other corals added at the same time?

 

[40g Nano]

The tank is about a month and a half old
I added coral before it

 

[40g Nano]

I added some coral at the same time, some before/after

 

[40g Nano]

They still aren't open today

 

[Fred2482]

It is hard to tell with the information provided. I would suggest to investigate light, flow and pests.

they are in the bottom right corner with the stock biocube 14 return pump and i have a kessil a80 that i turned down to about 25% and around 70% blue


do you think i should add copepods and phytoplankton because my nitrate is at 2

 

[Fred2482]

Not sure that would be the issue. What other coral do you have? Any other Zoas that are not having an issue? Any algae growing on them? It would be great to know all your parameters as well. As of now I would lean toward light, flow or pests....

[40g Nano]
