Tiger Oscars are a color variety of the Oscar Cichlid (Astronotus Ocellatus). Actual origins of the Tiger Oscar remain somewhat of a mystery with some information that suggests they were based from a naturally occurring color variety originally (incorrectly) classified (in 1904) as a separate species (Astronotus Ocellatus Zebra), a classification which is now obsolete. We know now, through additional DNA studies from 1986, that fish originally identified as Astronotus Ocellatus Zebra are actually Astronotus Crassipinnis (the second Oscar species). There is no viable evidence that these fish have any relation to the origins of the Tiger Oscar.

In the early 1800's, it wasn't uncommon that fish were collected, and taken to ichthyologists, sometimes hundreds of miles away. They relied on being told where the fish were collected, and sometimes the information wasn't exactly accurate. The scientific description evolved as follows; Cuvier, 1831, Jardine, 1843, Cope, 1872, Cope, 1878, var. zebra Pellegrin, 1904, Haseman, 1911 and finally to . means being marked with a star on the back, and bearing an "eye spot" marking. Plenty has been written on the possible function of these markings, but no acceptable conclusions have been drawn, and it hasn't been demonstrated that these markings have any function at all.
