Possibly three; you see, the exhibit was marked for both Bengal and Malayan tiger, and next door was another exhibit for a Sumatran couple. So if this is either a Bengal or Malayan, and the other species was in an off-exhibit area (i.e. they take turns in using the exhibit) you have three species.
possibly they put the malayan and bengal together. theres not mmuch difference between the two to an untrained eye. as long as they arent breeding them then its fine by me
