Etymology

Satanoperca: from the Ancient Greek Σατάν (Satán), meaning 'Satan' (the devil), and πέρκη (pérkē), meaning 'perch'. rhynchitis: from the Ancient Greek ρύγχος (…

Distribution

Known only from the Oyapock/Oiapoque, Approuague, Kaw, Kourou, Comté, Iracoubo, and Sinnamary river systems in French Guiana. Type locality is 'Crique Sikini, …

Habitat

Unconfirmed, but may inhabit environments with greater water flow than other Satanoperca species. More than 90% of French Guiana is covered by tropical rain fo…

Aquarium size

An aquarium with a base measuring at least 180 ∗ 60 cm or equivalent is required.

The most essential item of décor is a soft, sandy substrate so that the fish can browse naturally (see 'Diet').

Coarser materials such as gravel or small pebbles can inhibit feeding, damage gill filaments and even be ingested with the potential of internal damage or blockages.

Additional furnishings are as much a case of personal taste as anything else but the most favoured set-ups tend to feature relatively dim lighting plus some chunks of driftwood and scattered roots or branches.

Leaf litter is a typical feature of the natural environment but not really recommended in aquaria because the feeding behaviour of Satanoperca spp. tends to cause an excess of partially-decomposed material in suspension which not only looks unsightly but can block filter and pump mechanisms.

Water quality is of the utmost importance since these cichlids are extremely susceptible to deteriorating water quality and swings in chemical parameters so should never be introduced to a biologically immature aquarium. S. daemon also requires soft, acidic conditions and in most cases will not thrive in untreated tap water.

The best way to achieve the desired stability is to filter the tank using a combination of external canister filters and/or a sump system and perform minimum weekly water changes of 50-70%.

If the maintenance regime is insufficient health issues such as head and lateral line erosion or stunted growth can occur.

Mechanical filtration should also be tailored to trap small particles stirred up by the fish as sand can cause blockages and wearing issues with filter mechanisms if allowed to continually run through the system. High flow rates should be avoided so position filter returns accordingly.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Satanoperca spp. are benthophagous by nature, employing a method of feeding whereby mouthfuls of substrate are taken and sifted for edible items with the remai…

Behaviour and compatibility

Unless breeding this species is surprisingly peaceful and will not predate on fishes larger than a few millimetres in length. Suitable tankmates are numerous a…

Sexual dimorphism

Adult females tend to grow slightly smaller than males and are deeper-bodied when gravid.

Reproduction

This species is an ovophilous maternal mouthbrooder that has been bred in aquaria. There does not appear to be any particular trigger for the spawning process …

S. rhynchitis was previously referred to S. jurupari and known as S. sp. 'red lips' in the ornamental trade. It can be distinguished from congeners by the foll…
