What's happening to this alveopora?
it was doing good for a month and half untill two days ago
water quality has gone better
when it was introduced:
Nitrate: 32ppm
phos: 2.1ppm
Now:
nitrate: 17ppm
phos: 0.3
Any idea on what could cause this, it hasn't been moved or anything else
It's just hiding. Mine does that when Hermit crabs mess with it or when the flow changes. Sometimes they can hide for a couple of days and then come back out.
