Zoanthids not opening

[Sisterlimonpot]

Alright, So I've had these zoas for about 3 weeks and they are not fully opening up when the lights come on. All the other zoas in my tank are thriving and multiplying very quickly.

My water params are:
salinity 1.026
temp 80-82
PH 8.3
amm 0
nitrites 0
nitrates 5ppm
phosphates 0
calc 480
alk 9

I got the zoas from the same person I get all my others. They were open for a few days but closed up after that and haven’t opened since.
So are these zoas destined to die or will they open up eventually?

time will tell...the nitrates shouldn't bother them. Hope for the best. Someone with more knowledge will know more then I
