Geophagus means “eartheater,” and this species lives up to its name tag, spending much of its time rooting around the substratum and generally burrowing. It is tolerant of a wide range of water conditions, and has even been collected in oxygen-deficient, algae-laden, partially polluted water.
Distribution
- Atlantic coastal strip of Brazil, southward to the Rio de la Plata, Argentina.
Size
- Up to 11 in (28cm) reported; usually considerably smaller.
Behavior
- Territorial, but somewhat more tolerant than most of its close relatives, particularly of similar-sized tankmates.
Diet
- All foods accepted.
Aquarium
- Grain size of substratum should be sufficiently fine—at least in some areas—to allow for burrowing. Plants must be protected (by making the area around the base of the stems inaccessible). At least one large flat-topped or smoothly rounded rock should be provided. Water chemistry not critical, but soft-to-medium-hard, slightly acid water recommended. Temperature range: 68-81 F (20-27 C).
Breeding
- Eggs are laid on precleaned site, and both they and the fry are defended by the
