Zoas randomly shrunk over night

[lilly.hall]

Hi! I just checked my tank and I bought these Zoas 2 weeks ago. They have shrunk over night. My water Parameters are fine, and they never have opened up yet. I really was exited about them. Plus they were 30$

Well this can happen with corals but…
People will ask the normal questions, what are the current parameter, how often do you test, which test kits, tank age, pictures of tank currently under white light, flow, par and how many polyps on the frag?
If they never opened in the first place something is off

May be adjusting to tank, but how did you acclimate them to your tank ?
You say your readings are fine- What is your ammonia-nitrate-ph-salinity readingsa and what test kits are you using ?

if parameters were fine, they should be open by now, so as mentioned before, it would be best to list anything you can. it could be something as simple as nitrates and phosphates too high or maybe even too low, where normally, you might think they are ok, but could be part of the issue

Shrinking zoas are usually one of two things

Phosphates are above 0.2 and your method of testing is inaccurate

Zoas getting too much PAR, above 180

OHH ok so I just tested and my salinity was extremely high. Yikes.. I guess I should fix that
