Satanoperca lilith Breeding Guide
Breeding notes for the Amazonian eartheater Satanoperca lilith, whose reproduction is assumed to follow its close relative S. daemon as a biparental substrate-spawner.
Overview
Satanoperca lilith is an eartheater known from Brazil, where it is widely distributed along the Solimões/Amazon main channel between the río Japurá and río Tapajós, including the Ríos Negro, Branco, Madeira and Trombetas. Its reproduction is unreported but assumed to be biparental substrate-spawning, like that of its closest relative S. daemon. It is a demanding fish that is extremely susceptible to deteriorating water quality.
Sexing
External differences are minimal. Males typically attain larger sizes, while females tend to have slightly deeper bodies. Because reliable visual sexing is difficult, growing out a group and observing pair formation is the practical approach.
Conditioning
A biologically mature aquarium and strict water-quality management are essential, since the species is highly sensitive to poor conditions. Adults are conditioned on a varied diet appropriate for an omnivorous eartheater before any spawning attempt.
Breeding Setup
- Soft water with low hardness (reported general range around 18-179 ppm).
- Temperature in the maintenance range of 20-28 °C; pH 5.0-7.5, biased toward the softer, more acidic end for spawning.
- Fine sand substrate and clean, well-prepared flat surfaces suited to a substrate-spawning cichlid.
- A spacious, stable, mature tank, since deteriorating water quality is poorly tolerated.
Spawning Behavior & Trigger
Specific spawning details for S. lilith are not documented in the sources reviewed. Based on its closest relative, it is expected to clean a substrate surface and spawn as a biparental pair, with both adults participating in brood care.
Common Challenges
The main difficulties are the lack of documented aquarium spawning records, the need for very stable, soft water, and subtle sexing. The recorded breeding type for this species is substrate-spawner, consistent with the assumed biparental substrate-spawning strategy noted by the source.
