Not up on apistos but a few net searches throw up that its regarded as a mix of a resticulosa-complex and caetei-complex species.
They are apparently nearly 100% male, so breeding them will need exceptional luck, but they can breed with other apisto species such as borelli.
One source I read just said 'regular apisto care' ph 6.5-7.6 so I don't think they are that demanding, as long as water is clean and extremes avoided they should be fine.
Got most of my info from searches on 'apistogramma.com' forum. Hope this helps.
