Still having the problem? Sometimes mine dont open for a day but come back bigger and hungrier than ever the next day. What are your parameters? I've noticed if my temp or alk swings too much my candy canes and acans don't open as well
I tested them last week and they are fine. Nit=0, Amonia=0, PO4=0, Salinity=1.025. They are in my tank for three days. my next schedule for water change is this Sunday. Should I move them to difference spot/place?
