one of my pet preaves is when the foil push through covering, on frozen brine shrimp, or bloodworms, detaches from the packaging, and ends up in my shaker, and I don't notice it, and they end up in the aquarium... it's been months since that has happened, but of course I was in a hurry last night, and this morning I see two of them, one each in 2 tanks.... both are in a bad place to get them with the long tweezers ... my snail catching filter should be complete this next week, so maybe a gravel vacuum water change next week... may be the easiest way to get them out???
