The Apistogramma cf. pertensis is an amazing apisto from the amazon basin. Sometimes they are confused with the less common Apistgogramma pertensis.
Tank size should be around 25 inches in length, these fish grow to 2 inches and are fairly aggressive to other Apistogrammas if the space is too limited.
The tank should be full of hiding places and prefurably, understocked.
If you put a mirror in their tank they will show off in front of its own reflection. it will flare its gills and the colors will become intense.
Regular waterchanges and a low ph is a must.
