Help with Species Identification

[Audaxcity]

There are 5 nice images of species on Wikimedia Commons that I am having trouble identifying. Species IDs would help these images get some use.

[Ansorgii]

The first two images look like Oreochromis mossambicus. The males sometimes get these big mouths.

 

[duanes]

Agree with Ansorgii,
the last pic looks like it may be Vieja maculcauda
