help...green star polyp

[prosnow]

my green star polyps havnt come out in the past 2 days... :(
all tank stats are normal..
is it possible a hermit or emerald crab could have takin it out?

[niloc16]

this is totally normal. they go through stages. they will go a couple days without extending and then boom they'll be back. no worries. just watch them

I've found they won't open sometimes if your alk is too low.
What are your levels at? Ca, Alk, Mg?
