Fellow tank heads

Thanks you

Nothing.

Every so often, the genus' get updated as more research is done. They were classified as Amphilophusand now they're actually ex-Cichlasoma Festae...which I think of as like a catch all genus for cichlids they don't know where to put.

Taxonomic history:

Heros festae, Boulenger, 1899, original combination.
Heros (Heros) festae, Pellegrin, 1904, new combination.
Cichlosoma (Parapetenia) festae, Regan, 1905, new combination.
Cichlasoma festae, Eigenmann, 1922, new combination.
Nandopsis festae, Kullander, 1996, new combination.

That's from Cichlid room companion. They are currently listed as ex-cichlasoma.

Nothing they are one in the same. As some already stated, they were called both at different points in time. As of now they are ex-cichlasoma, however in the future they will be something else. Cichlids are always getting their genus changed and as Balton already informed you... the ex-cichlasoma genus is where they put cichlids they have not found a genus for yet or are in the process of doing more research on before placing them in another genus. It does get pretty confusing sometimes.

[cacichlids]

I think they should stay in Amphilophus... they resemble those more than anything else.

 

[balton777]

But they're even closer to Ornatum which aren't so much like other Amphilophus, or are they.

 

[cacichlids]

Both ornatum and festae are in the same situation... they don't know where to put them

Also described by Regan (1905), "Cichlasoma" (Amphilophus) ornatum is another species, like "C." atromaculatum, that has been misidentified in the hobby for reasons of its sheer rarity. Loiselle (1981), in his benchmark two-part article on South American cichlasomines, suggests that "C." ornatum resembles the Jack Dempsey ("Cichlasoma" octofasciatum) and that "its behavior and maintenance requirements are identical in all significant respects to those of the Jack Dempsey, with the proviso that C. ornatum appears somewhat less aggressive than C. octofasciatum in the cichlid community tank." It is also, according to Loiselle (1980), "less liberally marked with iridescent spangling than is that old aquarium favorite. Unlike the Dempsey, C. ornatum undergoes dramatic behaviorally related color changes."
