Agassiz's Dwarf Cichlid Care Guide Summary

The Agassiz's Dwarf Cichlid, scientifically known as Apistogramma agassizii, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 7.5 cm and have a compressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a medium level of biological waste.

To thrive, the Agassiz's Dwarf Cichlid requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 24°C and 29°C, with a pH range of 4.57 and a general hardness of 18 dGH. A low water flow is preferred. An aquarium test kit can help you monitor these values.

Due to its specialist needs, the Agassiz's Dwarf Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Male (Standard / Color Morphs) and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Agassiz's Dwarf Cichlid Habitat Setup

When setting up an aquarium for the Agassiz's Dwarf Cichlid, a low water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, driftwood, which can serve as both a hiding place and a dietary supplement, leaf litter or blackwater tannins to replicate their natural soft-water habitat, and dense planting to provide cover, break sightlines, and reduce stress. Browse aquarium sand substrate options to find the best fit.

Agassiz's Dwarf Cichlid Compatibility Notes

Classified as semi-aggressive, the Agassiz's Dwarf Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, ornamental shrimp are not safe companions, territorial behaviour may cause issues if hiding spots or floor space are limited, and boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Agassiz's Dwarf Cichlid Feeding & Diet Considerations

The Agassiz's Dwarf Cichlid will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups and will eat fry, so breeding efforts in the same tank are unlikely to succeed. Find quality Agassiz's Dwarf Cichlid fish food for this species.

Cockatoo Dwarf Cichlid

Apistogramma cacatuoides

Cichlids - South American
7.5 cm Semi-Aggressive

A highly popular and vibrant dwarf cichlid native to the Amazon basin. Named for the male's flamboyant, crest-like dorsal fin. They are cave-spawners that require a fine sand substrate (which they sift through their gills) and plenty of hiding spots. While generally peaceful in community tanks, they become fiercely territorial when breeding.

Freshwater Angelfish

Pterophyllum scalare

Cichlids - South American
15 cm Semi-Aggressive

The most iconic South American Cichlid, known for its distinct arrowhead shape and majestic fins. While domestic strains are hardy, they remain cichlids: they are semi-aggressive predators that will eat any fish small enough to fit in their mouths (like Neon Tetras). They form loose shoals as juveniles but pair off and become territorial as they mature. Height is more important than length for this species.

African Butterfly Cichlid

Anomalochromis thomasi

Cichlids - African
7.5 cm Mostly Peaceful

A peaceful, colorful dwarf cichlid from West Africa. Unlike many cichlids, it is plant-safe and generally suitable for community tanks. It is famous in the hobby as an efficient biological control for pest snails.

German Blue Ram

Mikrogeophagus ramirezi

Cichlids - South American
6 cm Mostly Peaceful

A strikingly colorful dwarf cichlid native to the Orinoco River basin. Famous for its vibrant blue spangles and peaceful demeanor compared to larger cichlids. They are strictly thermophilic (require high temperatures of 27-30°C / 81-86°F) and thrive in soft, acidic water. As 'earth-eaters' (Mikrogeophagus), they sift sand for food and form monogamous pairs.

Kribensis

Pelvicachromis pulcher

Cichlids - African
10 cm Semi-Aggressive

A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.

Bolivian Ram

Mikrogeophagus altispinosus

Cichlids - South American
8 cm Mostly Peaceful

A hardy and relatively peaceful dwarf cichlid native to the Amazon river basin. Compared to the popular German Blue Ram, the Bolivian Ram is larger, much more forgiving of water parameters, and prefers slightly cooler temperatures. They are eartheaters (geophagine) that sift through the substrate for food, making soft sand an absolute requirement to prevent gill damage.
