[Robert_Mid]

Hey to all, i don't know what's wrong with my Zoo's cause they are not opening since like 3 months ago the first colony begun to close and no open again. I bought a Mandarin Goby like 2 months ago cause i was watching at the night with a light lots of Amphipods and some fireworms, but the Mandarin didn't nothing to the porblem. I bought Activaded Carbon, water changes, move them to a safe place next to the frags that i have open as normal and just they don't want open!. Yesterday i put them with freshwater dips but nothing happend. So i need your help please.

Here are 2 pics:

My lighting is 4X65W PC's Current USA Satellite Fixture, i have also Tridacna, Mushrooms, Xenia, Palythoas, Anemone, Linckia Purple, Blue Tang, Percula, Mandarin, Turbinaria, Star Polyp and some more Zoo's but all them are doing great the only porblem is with this Zoo's specially the older one's.

Please help me i will really appreciate it!.

Try moving them up and down in the tank and with different amounts of flow until they are in a spot where they seem happy. Wait a few days before moving each time.

 

[Robert_Mid]

Ok so you suggest me move all them?.

Cheers!.

yeah move them or they are toast... thats a long time for them to not open..

 

[Robert_Mid]

For example wich place could be good for them?. Maybe the sand?.

Cheers!.

 

[Bebo77]

get them some good light and moderate flow....

 

[Robert_Mid]

I recently moved them like 1 moth ago to the sand and the same... nothing.

Cheers!.

I wouldn't put zoas in the sand

 

[Robert_Mid]

Why not?.

 

[Bebo77]

to little flow and light.. get some good like and descent flow trust me.. i have some 500+ zoas in my tank

 

[bassist6108]

the sand contact can also irritate them.

Ok so just a little bit of flow and light would be great?. I have 1 SEIO M620 and 2 Aquaclear 30 with Hydor both all them to max flow and my tank it's from 36G.

I just don't think they want to open. Maybe duds. Because zoas don't require too much light, nor too much water flow. Easiest to maintain. So if they don't want to open, they could just be duds. They don't look "perky" anyway. Because if the zoas don't want to open, they would still be pointing upwards. These particular ones are all drooped down and stuff... Could be duds.

 

[Robert_Mid]

So they could be dead?. That's weird cause they open just a bit somedays.

As long as there's some "tissue" there's hope, move them as advised Good luck

 

[Robert_Mid]

Cheers!.
