Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

This species has a relatively peaceful temperament compared to other Apistogramma members, making it one of the most docile dwarf cichlids. However, they are still territorial and will defend their chosen caves and immediate nesting sites, especially during the breeding season. Males can engage in minor skirmishes to establish dominance, but these are rarely harmful if sufficient space and cover are provided. Females can become hyper-aggressive toward any intruders, including the male, when guarding their eggs and fry.

Diet

Omnivore

Apistogramma borellii is primarily carnivorous, feeding on tiny invertebrates and benthic organisms in their natural habitat. In the aquarium, they thrive on a protein-rich diet consisting mainly of live and frozen foods such as brine shrimp, daphnia, cyclops, and bloodworms. While captive-bred specimens will often accept high-quality sinking pellets and flakes, these should only supplement their fresh diet. Feeding a varied diet is crucial for enhancing their vibrant coloration and ensuring successful breeding conditioning.

Life expectancy

2-5 years

Under optimal care and water conditions, Apistogramma borellii typically lives for 2 to 4 years in captivity. Providing a high-quality, varied diet rich in live and frozen foods is key to promoting their health and longevity. Stable, soft, and slightly acidic water chemistry, combined with low nitrate levels, will help them reach their maximum lifespan. In exceptional setups with pristine maintenance and minimal stress, some individuals have been reported to live up to 5 years.

Sex ratio

Harem

In the aquarium, Apistogramma borellii can be successfully housed as a single compatible pair or in a harem ratio of one male to several females. Keeping a harem (e.g., one male with three to four females) is highly recommended in larger, well-planted tanks to distribute any male attention and establish distinct territories for each female. If kept in too small a space or with incorrect ratios, dominant individuals may excessively harass submissive ones. In smaller tanks, keeping a single pair is often the safest stocking option to prevent intense territorial disputes.

Feeding frequency

Twice daily

It is recommended to feed Borelli's Dwarf Cichlid small portions once or twice a day. This feeding routine mimics their natural browsing habits and prevents overfeeding, which can lead to water quality issues and digestive problems like bloating. Spreading the food across different areas of the aquarium is beneficial to ensure that subordinate fish and females can feed without being intimidated by dominant males. During breeding conditioning, feeding frequency can be slightly increased with high-quality live foods to support egg production.

Bioload

Low to Medium

Borelli's Dwarf Cichlid is a small species with a relatively low biological load compared to larger cichlids, producing minimal waste. However, because they are sensitive to nitrates and organic pollutants, efficient mechanical and biological filtration is still required to maintain pristine water conditions. Regular weekly water changes of about 10-15% are highly recommended to ensure the parameters remain stable. A well-oxygenated environment with a mature filter is necessary to keep toxic ammonia and nitrite levels at zero.

Flow

Strong

In their native South American river basins, Apistogramma borellii inhabits slow-moving or still waters, such as quiet tributaries, margins, and oxbows. Therefore, they prefer weak to gentle water flow in the aquarium, as strong currents can stress them and exhaust their swimming energy. Filtration should be effective but set up in a way that minimizes heavy turbulence, utilizing spray bars or sponge filters if necessary. Creating calm areas with plants and driftwood will allow the fish to rest comfortably in their preferred low-flow spots.

Jump risk

Yes

Apistogramma borellii is not classified as a notorious jumper, but they can leap out of the water if startled, stressed, or chased by aggressive tank mates. This risk is particularly high during territory disputes, breeding conflicts, or when lights are suddenly turned on or off. To prevent accidental escapes, a secure, tight-fitting lid or cover is highly recommended. Utilizing floating plants can also create a natural barrier at the surface while helping the fish feel more secure in their environment.

Reproduction

Oviparous

Breeding Apistogramma borellii is relatively accessible to hobbyists compared to other dwarf cichlids. They are substrate spawners, with the female selecting a hidden cave, coconut shell, or crevice to deposit her eggs. The female takes sole responsibility for guarding the eggs and fry, displaying vibrant yellow warning colors and intense territorial defense. In smaller setups, the male may need to be temporarily removed after spawning to protect him from the female's nesting aggression. The fry can be fed newly hatched brine shrimp nauplii and microworms once they become free-swimming.

Compatibility & tankmates

Community

Borelli's Dwarf Cichlid is highly compatible with small, peaceful community tank mates that occupy the upper and middle water layers. Ideal companions include quiet characins, pencilfish, and small livebearers, which can also act as "dither fish" to make the cichlids feel more secure. Bottom-dwellers like Corydoras can be kept, but they may face aggression if they wander too close to the cichlids' breeding caves. Aggressive, large, or fast-swimming species should be avoided, as well as other Apistogramma species to prevent territorial fights and potential hybridization.

Tank level

Middle/Bottom

This species primarily occupies the bottom and lower-middle levels of the water column, where they spend their time foraging for food and defending territories. They are closely associated with the substrate, preferring sandy areas decorated with leaf litter, driftwood, and low-lying caves. While they occasionally venture to the middle or upper layers of the tank during feeding times, their daily activities are concentrated near the tank floor. Providing ample cover in the lower zone helps them feel secure and exhibit natural behaviors.
