need to wait more then 10 mins.. cos after only 10 mins. few started struggling and coming / going back into the zoas..
so i make sure i dipped longer so as everything inside will up lorry.
then i shake and wash with salt water, put in.
all the zoas have no side effect (from what i observe)..
somemore, the pic i took, is only a few, got bristle worm (small and tiny) and many other small critters didnt have chance to scoop it up)
