Pertensis Dwarf Cichlid yellow (Apistogramma sp. pertensis) — 3-4cm

Overview

The apistogramma tank mates debate often highlights species that combine manageable size with bold personality, and Apistogramma sp. pertensis yellow fits the bill perfectly. This striking yellow dwarf cichlid, a colour variant of the pertensis complex, is a showstopper in planted aquariums and soft-water biotopes. Originating from the Amazon Basin, though the exact wild locality for this vibrant colour form remains uncertain, this 3cm gem brings vivid golden hues, intricate behaviour, and rewarding breeding potential to the aquarist's attention. Available for sale UK through specialist suppliers, the yellow pertensis is a must-have for enthusiasts seeking rare, colourful dwarf cichlids that thrive in carefully maintained soft-water conditions.

Appearance

Apistogramma sp. pertensis yellow is immediately recognisable by its brilliant golden-yellow body coloration, which intensifies in mature, healthy males. The body is laterally compressed with elegant, flowing fins. Males develop extended dorsal, anal, and caudal fins with intricate patterning—often featuring dark edging, iridescent highlights, and contrasting markings. Females are smaller and less flamboyant, displaying a more subdued yellow or cream coloration, though they too exhibit beauty when guarding fry. The species' colour is most vibrant in soft, tannin-stained water with subdued lighting and a dark substrate.

Natural Habitat

While the exact wild origin of this yellow colour form is uncertain, the species complex is associated with blackwater tributaries, flooded forests, and shallow pools in the Amazon Basin. These environments feature soft, acidic water rich in tannins, minimal water flow, and abundant organic debris such as leaf litter and submerged wood. The substrate is typically fine sand or silt, and dense vegetation provides both cover and foraging grounds for small invertebrates. Replicating these conditions is essential for unlocking the species' full potential in captivity.

Aquarium Setup

A minimum 40-litre aquarium is sufficient for a pair or small group, though larger is always better for reducing territorial conflict. Use fine sand substrate and incorporate driftwood, Indian almond leaves, and smooth stones to create caves and hiding spots. Dense planting with soft-water species such as Cryptocoryne, Anubias, and floating plants diffuses lighting and provides visual barriers. Gentle filtration through a sponge or small canister filter maintains water quality without excessive current. Tannin-stained water not only enhances coloration but also mimics the fish's natural environment, supporting health and reducing stress.

Water Parameters

This species is sensitive to water chemistry and demands soft, acidic conditions. Maintain temperatures between 24-27°C and pH from 5.5-7.0, with low hardness. Regular partial water changes with dechlorinated, properly conditioned water are critical. Avoid sudden fluctuations, as stress can trigger disease. Efficient biological filtration and low nitrate levels (under 20 ppm) are essential for long-term health. Test water parameters regularly and adjust as needed to maintain stability.

Feeding

A carnivore by nature, Apistogramma sp. pertensis yellow thrives on a protein-rich diet. Offer high-quality micro pellets or granules formulated for dwarf cichlids, supplemented with live or frozen foods such as bloodworms, daphnia, brine shrimp, and small insect larvae. Occasional plant-based matter or algae-based foods can be offered but are not essential. Feed small portions twice daily, removing uneaten food to prevent water quality degradation. Variety is key to vibrant coloration and optimal health.

Behaviour

This semi-aggressive dwarf cichlid exhibits classic Apistogramma behaviour: males are territorial, particularly during breeding, and establish small domains around caves or other focal points. Aggression is usually limited to displays and posturing, especially in well-planted tanks with ample hiding places. Females are less territorial but become fiercely protective when guarding eggs or fry. The species is generally peaceful toward non-competing tankmates and spends much of its time exploring the substrate and lower water column.

Tank Mates

Ideal companions include small, peaceful schooling fish such as tetras, rasboras, and pencilfish, which occupy the upper and mid-water levels. Bottom-dwellers like Otocinclus and peaceful dwarf catfish are usually compatible in larger aquariums. Avoid large or boisterous fish, aggressive cichlids, fin-nippers, very active bottom dwellers, and large predatory species. Ensure all tankmates share the same soft-water requirements.

Breeding

Breeding Apistogramma sp. pertensis yellow is a rewarding experience for aquarists. Spawning typically occurs in a cave or sheltered crevice, where the female deposits eggs on a flat surface. She then guards and fans the eggs while the male defends the surrounding territory. Eggs hatch in 2-3 days, with fry becoming free-swimming after about a week. Feed fry on infusoria or specialised liquid fry food, gradually transitioning to newly hatched brine shrimp. Soft, acidic water and stable conditions are critical for successful breeding and fry development.
