Question for those with anemones.

I have four BTA anemones (originally one which has split three times)!
Occasionally I'll find a glob of matter floating around the tank ...
the best I can describe it is that it looks like a large, soft, pulpy
lima bean, often with trailing strings. Am I correct in guessing that
this is not-fully-digested food ejected from an anemone? It really
disgusts my wife. ;-) I pull it out and throw it away so it won't
foul the water.

Thanks.
