Water parameters
Overview
The red-breasted acara is one of the smallest species in the genus Laetacara. Dorsigera ("carrying on the back") in its scientific name refers to the dark spot in the middle of the dorsal fin. During breeding the throat, cheeks and belly of both male and female turn bright red. Thanks to its southern range, it tolerates cooler water than many Amazon dwarf cichlids; its color pattern differs somewhat between populations.
Tank Setup
- At least 60 liters for a pair.
- 23–26°C; soft to moderately hard, pH 6–7.5.
- Fine sand, flat stones and broad-leaved plants (spawning surfaces), roots and plants along the edges.
- A 25% water change every week.
Diet
Omnivorous. It feeds on small sinking granules, flake food, frozen brine shrimp, daphnia and bloodworms; it also takes plant-based foods.
Behavior and Compatibility
Peaceful and calm; it spawns on open surfaces, and the male and female care for the eggs and fry together. During breeding it guards a small area but rarely harms other fish. It may eat shrimplets.
Good companions: small tetras, pencilfish, Corydoras, otocinclus, dwarf gouramis.
Avoid: aggressive and large cichlids, fast and domineering barbs.
