Acro tips gone slightly white?
A few days ago the tips of one of my acros went white but only on a few of the branches:
sorry about picture quality.
it has stopped going white, as i had lowered the lights about 3" and have raised them back up again and this was the only one that showed signs of change. Is this bleaching or is it the coral changeing colour (i already think i know the answer) but the polyps are still showing good extension and look happy. Is there anything i should do?
Its quite weird as i frag
i took of it which i placed in a higher position showed no sighns of change?
