Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) Care Guide Summary
The Barlow's Dwarf Cichlid (Apistogramma Maulbrüter), scientifically known as Apistogramma barlowi, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 6.5 cm and have a fusiform body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a low level of biological waste.
To thrive, the Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) requires a freshwater only aquarium with a minimum volume of 54 litres and a tank length of at least 60 cm. Water temperature should be maintained between 22°C and 29°C, with a pH range of 4.5–6.5 and a general hardness of 1–5 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male (Red Form / Glaser), Male (White Form / Hauswel), 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.
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) Habitat Setup
When setting up an aquarium for the Barlow's Dwarf Cichlid (Apistogramma Maulbrüter), a moderate water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and 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, and leaf litter or blackwater tannins to replicate their natural soft-water habitat.
Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) Compatibility Notes
Classified as mostly peaceful, the Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) 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 and mid-level zones can help reduce competition and territorial overlap.

Fish Similar to Barlow's Dwarf Cichlid (Apistogramma Maulbrüter)
Apistogramma Mouthbrooder (Maulbrüter)
Apistogramma barlowi
Formally described as Apistogramma barlowi, this species is highly unique among Apistogramma. Unlike its cousins who are strict cave-spawners, the Maulbrüter is a facultative larvophilous mouthbrooder. They spawn in caves, but once the eggs hatch, the female (and occasionally the male) will gather the larvae in their mouths to protect them. They require soft, acidic blackwater conditions and sandy substrate.
Apistogramma Resticulosa Mamor
Apistogramma cf. resticulosa Mamor
The Apistogramma cf. resticulosa 'Mamor' is a peaceful but territorial dwarf cichlid originating from the Mamoré River basin in South America. Known as the 'Thin-line Dwarf Cichlid', they require soft, sandy substrates for sifting and complex environments with driftwood and leaf litter to establish territories. While generally peaceful in community tanks, they become highly aggressive during spawning and will hunt dwarf shrimp.
Banded Apistogramma
Apistogramma bitaeniata
A stunning South American dwarf cichlid native to the blackwater streams of the Amazon basin. Known for their distinct dual lateral stripes, they are a bottom-dwelling species that requires soft, acidic water, sandy substrate, and complex environments with caves or leaf litter. They are generally peaceful in a community tank but highly territorial towards other bottom-dwellers, especially when breeding.
Apistogramma Resticulosa Marmor
Apistogramma cf. resticulosa "Marmor"
A striking, small South American dwarf cichlid originating from the Rio Mamoré basin. The 'Marmor' (marbled) variant is highly sought after for its metallic colors. They are peaceful community fish but become highly territorial when breeding. They require a soft, sandy substrate which they sift for food, and thrive in soft, acidic water with plenty of cover.
Apistogramma Marmor (Marbled Apisto)
Apistogramma erythrura
The Marbled Apisto is a beautiful, diminutive South American dwarf cichlid. Like most Apistogramma species, they are bottom-dwelling micropredators that naturally sift through fine sand and leaf litter for food. They require soft, acidic water, gentle flow, and plenty of visual barriers like driftwood and caves to feel secure. As harem breeders, a typical setup includes one male and several females.
Hongsloi Apistogramma
Apistogramma hongsloi
A striking dwarf cichlid native to the Orinoco River basin in South America. They are popular for their vivid red, yellow, and blue colors. Best kept in blackwater setups with soft, acidic water and plenty of leaf litter. They form harems and require sand substrate, as they sift sand through their gills to find food.
