one of my zoas has been closed up and got these two little white dots. they don’t look like zoa pox. possibly sponge?

hey yall am not really sure what’s going on w these zoas, all my other ones are opening up fine. here are my parameters
ammo:0.0
nitrate:0.1
nitrite:0.0
phosphate:lower than .1 but not quite 0 (using API phosphate test)
i do not test alk,calcium, or mg as this is mainly a softie tank. the zoa in question is near a kenya tree and toadstool however carbon was replaced recently and those seem unbothered
