Species description

Care, breeding and tankmates

Fish profile

Temperament

Territorial

Overall, they exhibit a peaceful demeanor towards other species, but they are known to be territorial among their own kind. During the breeding season, both sexes become fiercely protective of their spawning sites and fry, potentially showing aggression to any intruders. Outside of breeding, they are somewhat shy and require a complex environment with plenty of hiding spaces to feel secure. Creating distinct visual barriers helps manage their territorial nature.

Diet

Carnivore

In their natural habitat, they are micro-predators that sift through the substrate for small invertebrates, insect larvae, and zooplankton. In captivity, they should be offered a varied and high-quality diet consisting of sinking micro-pellets and flakes. Supplementing their diet regularly with live or frozen foods like daphnia, baby brine shrimp, and bloodworms will promote optimal health and vibrant coloration. Variety is key to preventing nutritional deficiencies.

Sex ratio

Harem

In a suitably sized aquarium, they are best maintained in a harem configuration consisting of one dominant male and several females. If the tank is on the smaller side, maintaining a single compatible pair is the safest approach to minimize intraspecific aggression. Keeping multiple males usually requires a very large footprint with complex hardscape to break lines of sight and establish distinct territories. Proper sex ratios are vital for a peaceful tank.

Feeding frequency

Twice daily

It is highly recommended to feed them small portions once or twice daily to maintain their metabolism and overall well-being. Care must be taken to only offer an amount they can completely consume within a couple of minutes to avoid fouling the water. Overfeeding is a common mistake that can lead to severe water quality issues. Fasting the fish for one day per week can also help clear their digestive tract.

Bioload

This species has a relatively low bioload compared to larger cichlids, making it suitable for appropriately sized setups. However, they are highly sensitive to deteriorating water conditions and elevated nitrates. Maintaining pristine water quality through adequate filtration and regular water changes is absolutely crucial for their long-term health. A heavily planted tank can also help absorb excess nutrients and keep the environment stable.

Flow

Moderate

Originating from slow-moving streams, backwaters, and sluggish tributaries, they strongly prefer gentle water flow in the aquarium. Strong currents will cause them undue stress and force them to expend unnecessary energy just to maintain their position. Filtration should be baffled if necessary to provide a calm environment, particularly near the substrate where they spend most of their time. Mimicking this natural calm flow is essential for their comfort.

Jump risk

No

Reproduction

Oviparous

They are typical cave spawners, utilizing secluded crevices, leaf litter, or natural hollows to lay their eggs. The female assumes the primary responsibility of guarding the eggs and the subsequent fry, often becoming highly reclusive. The male's role involves defending a larger peripheral territory against any perceived threats. Providing plenty of hiding spots like coconut caves, PVC pipes, and dense vegetation is critical for successful breeding.

Compatibility & tankmates

Aggressive

They are best kept in a species-specific aquarium or a peaceful community tank with small, non-aggressive dither fish like tetras or rasboras. Fast-swimming or boisterous tank mates should be avoided as they will easily outcompete this species for food and induce stress. Bottom-dwelling species such as Corydoras might face territorial disputes, especially if breeding behaviors commence. Careful selection of tank mates is necessary to ensure a harmonious environment.

Tank level

Bottom

These fish primarily inhabit the lower third of the water column, spending the vast majority of their day navigating the substrate. They are often seen foraging among leaf litter, driftwood, and plant roots in search of food. They rarely venture into the upper levels of the aquarium unless enticed by feeding or if they lack sufficient cover below. A well-structured bottom layout is highly appreciated.
