The larger one is some type of gibberosa, but can't see the mask and facial markings clearly enough to definitely say what type. Smaller one probably is also, but I'm not 100% certain from that photo.
Just two in a tank, even a male and female, can be problematic. They're not a pairing fish and a male can be hard on a single female (or a another male for that matter). Might already be some evidence of that with the rough looking dorsal on the smaller fish. It's sometimes possible to keep just two in a tank, even to have them spawn and produce fry, but it's not a given and ime if it's going to work you need some clever rock scaping to have it work. On that note it looks like you have them divided.
