Redbreast acara care

About this species

Laetacara dorsigera (Heckel, 1840) belongs to the family Cichlidae and is known as the redbreast acara. Older combinations include Acara dorsiger and Aequidens dorsiger. The current specialist profile describes a length of around 37 mm standard length. FishBase lists 6 cm SL; because these figures differ, adult size is treated cautiously and the measurement basis is retained.

Breeding fish are notable for red cheeks, opercula and belly. Populations can differ in colour pattern. Where possible, obtain fish of known origin and keep distinct local forms separate.

Natural habitat

The distribution includes the Guaporé in Bolivia and western Brazil, the Paraná system in southern Brazil, Paraguay and Argentina, and the Uruguay River in Brazil’s Rio Grande do Sul state. This broad range does not mean every local habitat has identical conditions. The care values used here come from the current Seriously Fish species profile, rather than an assumed average across all localities.

Aquarium and layout

The current Seriously Fish profile does not record a minimum, but two specialist hobby sources (Zoopet and Nordiska Ciklidsällskapet) independently recommend 60 cm length and 80 litres. Treat this as a cautious starting minimum; a breeding pair with tankmates needs more usable space. Arrange the aquarium with plants, wood or other visual barriers, sheltered areas and open swimming space. Provide suitable flat surfaces and quiet corners where a pair can select a spawning site. Account for territorial behaviour around that site when breeding, and avoid allowing one pair to dominate the entire available bottom area.

A mature, stable aquarium matters more than chasing an unsupported figure outside the documented ranges. Use calm filtration that removes waste without exposing every sheltered area to strong flow.

Water conditions

Seriously Fish lists 20–28 °C, pH 5.0–7.5 and 2–15 dGH. FishBase gives a narrower temperature interval of 20–23 °C for one cited reference. Rather than resolving that difference with an unsupported optimum, this guide uses the wider range in the current specialist profile; stable conditions within the appropriate range are the practical choice. Acclimate gradually and avoid rapid changes in temperature or water chemistry.

Behaviour and group size

Seriously Fish describes the species as best kept in a pair and generally compatible with other fish, while detailed compatibility information is missing. No named tankmate is therefore presented as a proven combination. Expect a pair to defend a substrate site while breeding. Provide visual barriers and retreat space, and be prepared to separate fish if persistent injuries or food blocking occur.

A peaceful community is appropriate only when the size, behaviour and space needs of every species fit; overlapping water values alone do not establish compatibility.

Feeding

In the wild, the species probably forages on algae, organic detritus, small insects, worms, crustaceans and other zooplankton. Seriously Fish reports that it is readily fed in aquaria. Offer variety, including small live or frozen foods such as bloodworm, Daphnia and Artemia, alongside quality dried flakes or granules. Include some food with plant or algal content. Feed portions that are eaten promptly and remove leftovers to protect water quality.

Breeding

Laetacara dorsigera is a biparental substrate spawner: both parents take part in reproduction and brood care. Provide sheltered areas and suitable surfaces, and avoid unnecessary disturbance once a pair has chosen a site. The parents may defend that area, so watch the space and behaviour of other inhabitants. The consulted specialist profile does not provide a complete egg and fry protocol; specific counts, timings or rearing values are therefore not supplied.
