Yellow Head Borelli Dwarf Cichlid (Apistogramma borellii)

Overview

Yellow Head Borelli Dwarf Cichlid is a colour form of Apistogramma borellii, a South American dwarf cichlid valued for its calm manner, cooler-water tolerance and bright male colour.

This is one of the more approachable apistogrammas for a planted community or specialist dwarf-cichlid aquarium. It still behaves like a cichlid, especially around caves and fry, but it is usually less forceful than many larger South American cichlids. The best results come from a mature tank with soft to medium water, shaded cover, small peaceful tank mates and a layout that gives the fish a territory without making the whole aquarium feel crowded.

Quick Facts

• Scientific name: Apistogramma borellii.
• Trade form: yellow head / Borelli dwarf cichlid.
• Adult size: usually around 4-6 cm, with males larger and more colourful than females.
• Care level: moderate; hardy for an apisto, but still needs a mature aquarium.
• Temperament: peaceful to mildly territorial, especially during breeding.
• Minimum aquarium: around 60-75 litres for a carefully planned pair or single male, with more floor area preferred.
• Water: 20-26C for general care; pH 6.0-7.5; soft to medium hardness.
• Diet: small quality foods, especially micro-pellets, frozen cyclops, daphnia, artemia and bloodworm in moderation.

Appearance

Males show the strongest yellow head colour, blue-green body sheen and extended fin rays. In good condition they can become a vivid centrepiece without needing the size or aggression of larger cichlids. Females are smaller and more understated until breeding, when they can turn bright yellow and become assertive around a cave or fry cloud.

Colour depends on maturity, lighting, background, diet and confidence. A dark substrate, floating plants and broken lines of sight often show the fish better than a bright bare tank.

Natural Habitat And Water

Apistogramma borellii is associated with the Paraguay River basin and lower Paraná system. Compared with many apistogrammas, it is comfortable in cooler subtropical conditions, which is one reason it is popular with planted-tank keepers who do not want very warm water. Clean, stable water matters more than chasing an extreme number.

Use a mature filter, gentle flow and regular water changes. Soft, slightly acidic to neutral water is ideal, but many captive-bred fish adapt well if hardness and pH are stable. Avoid newly set-up aquariums, ammonia or nitrite exposure, and sudden parameter swings.

Aquarium Setup

Think in terms of floor space and shelter. Fine sand, leaf litter, small caves, coconut shells, wood, plants and shaded corners all help this dwarf cichlid feel secure. A low, long aquarium can work better than a tall narrow one because apistogrammas live and defend space near the bottom.

Provide more than one potential cave, even if keeping a pair. The female will choose the site she likes, and spare cover lets the male or tank mates move away when she is guarding eggs or fry. Floating plants or dimmer lighting help reduce stress and bring out colour.

Feeding

Feed small foods that match the mouth size. A quality micro-pellet can be the staple, but this fish looks and behaves better when offered variety: frozen daphnia, cyclops, artemia, small bloodworm portions and similar foods. Avoid large hard foods and heavy feeding that leaves waste in the substrate.

Because apistogrammas feed near the bottom, make sure quick midwater fish do not take everything first. Small calm tetras, pencilfish or rasboras can work well, but the dwarf cichlid still needs time to feed.

Behaviour And Tank Mates

Yellow Head Borelli is suitable for a peaceful, planted community when stocked thoughtfully. Good companions include small calm schooling fish that enjoy similar water, and peaceful bottom fish only if the tank has enough floor area. Avoid large cichlids, aggressive fish, fin nippers, boisterous fast feeders and anything small enough to be treated as prey.

During breeding, the female may guard a cave and push away fish that come too close. This is normal cichlid behaviour, not a reason to cram the tank with more hiding places at random. The aquarium should already have territories, shade and escape routes before breeding starts.

Breeding Notes

This species is a cave spawner. The female usually cares for eggs and fry closely while the male guards a wider area. Soft, clean water and quiet surroundings help, but breeding should not be encouraged unless the tank has space for territorial behaviour and a plan for fry.

If you simply want a display fish, a single male can be a sensible option in a calm community. A pair or trio can be rewarding, but it needs more thought, more cover and closer observation.
