Zoa melting/shrinking away

[Duncan Tse]

Can anyone help me figure out what the problem is with my pink halls zoas?

Got it last month from a local reefer and ever since its been in the tank, they seem to be melting away but all my other corals are doing fine.

Alk : 9
Cal : 420
Mg : 1320
NO3: 10
PO4: 0.1

Getting roughly around 100par in the area

Following a long as all of my zoas have suddenly closed up and have not reopened in several days.

The ones you do have a really nice looking

Whats your salinity?

Maybe they dont like the neighbors. I wouldnt worry about it. Those other ones will fill that area in nicely.

You can test this by obviously moving them. They might not like the flow or maybe it's too bright for them. Theres a million reasons however my guess is its neighbors.

If your actually losing heads a hydrogen peroxide bath may help clean it up

Thank you!

It's at 1.026

Thanks for the advice. I will try to dip and then move it to my frag rack to see if it'll make it.

can you be more specific?

Yeah a 4:1 ratio. You dip the zoa in and it will bubble and kill anything that doesn’t belong. I did like 5 min. Than I swished it in a bucket of tank water.

 

[habavonc]

4:1 with 3%. ?

Zoas are weird. You can have whole colonies of zoas doing well while one just melts away for no reason. I've had this happen a few times.

Seems like any new zoas don't like me at all.

Got this rainbow infusion zoa looking all nice and happy on my frag rack. Left it there for a couple days and all is good until I glued it down to my rockwork.

Been closed up like this for the past few days.

Only problem I can think of is that my Mg somehow dipped down to 1200 and I test weekly... It was at 1300 last week but somehow it managed to drop 100ppm in a week. Not sure how that is even possible. I triple checked and I'm getting a consistent 1200ppm Mg.

Can't seem to figure out what the problem is as all my other zoas are doing fine.
