Yes, a sea anemone has a single opening to the digestive tract. This single opening acts as a mouth for feeding and an anus for excreting waste products.
Leeches have a complete digestive tract. Leeches are members of Phylum Annelida. This phylum has the general characteristic of having a complete digestive tract, i.e. food goes in through the mouth, pass through digestive tract of some sort like stomach and/or intestine, waste gets discarded through some sort of rectal opening, i.e. anus. In comparison, an incomplete digestive tract generally means food goes in and waste come out of the same opening, i.e. mouth=anus. Lower level invertebrates have incomplete digestive tract like Phylum Cnidaria and Phylum Platyhelminthes members.
