Borelli Dwarf Cichlid yellow head (Apistogramma borellii) — 3-4cm

Overview

The Borelli dwarf cichlid (Apistogramma borellii) is a colorful, relatively cool-water species from the Paraguay River and Paraná River basins of South America. This charming fish is highly regarded in the tropical fish shop UK market, prized for its peaceful nature, striking yellow-headed males, and adaptability to cooler water temperatures than most apistogrammas. Available as South American dwarf cichlid for sale UK, this species is found further south than most other genus members, naturally inhabiting temperate to subtropical regions of southern Brazil, Paraguay, Bolivia, and northern Argentina. With an adult size of just 4 cm, the Borelli dwarf cichlid is ideal for nano and moderate-sized community aquariums. For aquarists seeking a colorful, engaging dwarf cichlid that tolerates cooler conditions, A. borellii is an outstanding choice.

Appearance

Apistogramma borellii males display striking coloration with a brilliant yellow head and throat that contrasts beautifully against a pale grey or blue-grey body. The dorsal fin is elongated and may show red, orange, or blue accents. Breeding males intensify their coloration dramatically, becoming especially vivid. Females are smaller and more subdued, typically showing a yellowish hue when guarding eggs or fry. Both sexes have large, expressive eyes and a graceful body shape. The overall appearance is refined and attractive, with the yellow-headed males being particularly eye-catching.

Natural Habitat

Apistogramma borellii inhabits slow-moving streams, tributaries, and flooded areas in the Paraguay River and Paraná River basins of southern Brazil, Paraguay, Bolivia, and northern Argentina. These habitats are characterized by soft to moderately soft water, abundant leaf litter, submerged roots, and aquatic vegetation. The species experiences seasonal temperature variations and has evolved to tolerate cooler water than most tropical apistogrammas. Water flow is typically minimal, and the environment provides ample cover.

Aquarium Setup

This species tolerates cooler water better than many apistogrammas but still needs stable, clean conditions, low nitrate, and plenty of hiding places. Provide sand or fine substrate, leaf litter, driftwood, caves, and live plants to create a naturalistic environment. Filtration should be efficient but gentle, with regular water changes to maintain excellent water quality. A minimum tank size of 75 litres is suitable for a pair or small group. Avoid bright lighting and strong water currents.

Feeding

As an omnivore, Apistogramma borellii requires a varied diet. Offer quality micro-pellets as the staple, supplemented with frozen or live foods such as daphnia, brine shrimp, bloodworms, cyclops, and insect larvae. Supplement with occasional vegetable matter such as spirulina flakes. Feed small portions multiple times per day to maintain optimal health and conditioning. A varied diet supports optimal coloration and breeding behavior.

Behaviour and Temperament

Apistogramma borellii is semi-aggressive, with males defending small territories around caves or spawning sites. Females guard eggs and fry, with males defending a wider territory during breeding. Despite their territorial tendencies, this species is relatively peaceful and one of the more community-friendly apistogrammas. They spend much of their time near the substrate, exploring cover and sifting sand. Soft, slightly acidic water with plenty of cover improves breeding success.

Tank Mates

Choose peaceful tankmates that share similar water requirements and temperature tolerance. Small peaceful schooling fish such as tetras, rasboras, and pencilfish, peaceful bottom dwellers such as small Corydoras species, small non-aggressive livebearers in suitably sized tanks, and peaceful invertebrates (though shrimp may be eaten) are suitable. Avoid large or boisterous cichlids, aggressive territorial fish, fin-nipping species, large predatory fish, and very active fast-feeding fish.

Breeding

Spawning usually occurs in a cave or sheltered crevice. Females guard eggs and fry, while males defend territory. Soft, slightly acidic water (pH 6.0-6.5) with plenty of cover improves success. Eggs hatch in approximately three days, and fry become free-swimming several days later. Fry require very small live foods such as infusoria or newly hatched brine shrimp. Males may become territorial during breeding, so provide ample hiding places.
