Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

They exhibit a calm, curious, and largely peaceful temperament, making them an ideal centerpiece for a community tank. While they will defend their small territory, especially during spawning, they rarely cause physical harm to other species. Their engaging personalities and interesting substrate-sifting behaviors make them highly rewarding to keep.

Diet

Omnivore

Bolivian Rams are omnivorous micropredators that sift through the substrate for small invertebrates. A high-quality diet of sinking cichlid pellets or granules should form the staple of their meals. This must be supplemented frequently with frozen or live foods such as bloodworms, daphnia, and brine shrimp to ensure optimal coloration.

Sex ratio

Solitary

They are best kept either as a single specimen or a confirmed male-female pair. While generally peaceful, males will establish small territories and may squabble if the tank is not large enough to accommodate multiple territories. If attempting to form a pair, purchasing a group of juveniles and letting them pair off naturally is the most successful method.

Feeding frequency

Twice daily

It is best to feed them small amounts two times a day, ensuring that food reaches the bottom where they prefer to feed. Due to their deliberate eating style, they can easily be outcompeted by fast-swimming top feeders. Target feeding may be necessary if they are kept in a busy community tank.

Bioload

The Bolivian Ram produces a moderate bioload typical for a dwarf cichlid of its size. Because they require pristine water conditions to thrive, efficient biological filtration and regular water changes are absolutely necessary. Although hardier than their German Blue Ram cousins, high nitrate levels will still compromise their immune system over time.

Flow

Stagnant

They prefer sluggish to moderate water movement, replicating the slow-moving rivers and pools of their native South American habitat. Strong currents will force them to expend unnecessary energy and cause chronic stress. Baffling filter outputs or using sponge filters helps create a suitably calm environment.

Reproduction

Oviparous

They are substrate spawners that form monogamous pairs and provide excellent bi-parental care. The female will lay her eggs on a flat, cleaned stone or a broad plant leaf, which the male then fertilizes. Both parents will fiercely defend the eggs and the resulting free-swimming fry from any potential predators.

Compatibility & tankmates

They are remarkably peaceful cichlids that do wonderfully well in community aquariums with other non-aggressive fish. Excellent tank mates include small to medium-sized tetras, rasboras, and corydoras catfish. They should not be kept with overly boisterous or aggressive species that will outcompete them for food or bully them.

Tank level

Middle/Bottom

Bolivian Rams are predominantly bottom and lower-mid level dwellers. They spend a significant portion of their day sifting through the sand, searching for morsels of food. Providing a soft, sandy substrate is crucial, as sharp gravel can severely damage their delicate gills during this sifting behavior.
