But how long do they keep them in Fishless systems? Believe they obtain direct from local rock pools yet doubt they place each capture into their own separate 70 plus day compartment.Technically yes, but check out Reef Cleaners, they keep their Cuc in fishless systems. I just acclimate them and drop them in the tank.
You will have to qt coral and nems though. Some sell it already qt online like dr reef. But it’s cheaper to do it yourself.
Rule in QT being clock starts with last addition.
