I also used a soft toothbrush to lightly clean the shell (not the foot!) to dislog any snails, aiptasia, etc.). I quarantined for a few days of oservation for pyramid snails. I had it under VHOs for QT, which I figured was Ok, but not suitable for too long. I kept it there for 10 days and spent a lot of tiem with a magnifying glass looking for pyramids.
