If you don't have a lot of them.I take them out and feed them in a bowl.That way you won't over pollute your tank.Just a little tip here for you.Just don't expose them to the air.Some of these guys will only put their polyps out when it's dark.If doing it in the day time,just put a towel over your bowl.Poyps will pop out for you then, target feed.
