I have 4 of these wonderful fish. As I am an eartheater fanatic I also keep brasiliensis, surinamensis, balzanii and steindachneri. The jurapari will prefer a tank of at east 4ft with a substrate fine enough to allow them to take it in and expel it through their gills (about 1-3mm). It is too large if they expel it through their mouths. They will readily take pellets such as Hikari, or for good colour use Spectrum. They appreciate bloodworms etc.
The eartheaters are not a solitary fish and do best in small groups (they are never found solitary in the wild unless sick or injured). I keep all my eartheaters in groups of six fish, and they should live happily with other eartheaters or South americans such as Blue Acara. Rockwork and driftwood should be provided but sparingly, as it is more important for them to have room to sift the substrate. Conditions should be as for most South american cichlids, around neutral is fine or slightly acidic. A power filter is a must, as their constant digging will stir up debris.
An excellent book for eartheater is "South American Eartheaters" by Thomas Weidner.
