I just bought a piece of zoo today.
when i first put it into my tank, the polyps opens up for a while. but soon after,
around 20 mins, all the polyps closed.so far, it remains closed.
the last time i tried 1 zoo, it closes and becomes mouldy like and i tink it died.
how how?
im running on 55W PL blue light. the zoo is placed on the sandbed. my tank is 1.5ft height with dsb of around 3-4inch.
my anemone all doing ok...
and i tot zoo is supposed to be one of the easiest coral to keep?
