Checkerboard Cichlid Care Guide Summary
The Checkerboard Cichlid, scientifically known as Dicrossus filamentosus, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 8 cm and have a fusiform body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a low level of biological waste.
To thrive, the Checkerboard Cichlid requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 24°C and 30°C, with a pH range of 4.5–6.5 and a general hardness of 1–5 dGH. A low water flow is preferred.
Due to its specialist needs, the Checkerboard Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Male and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Checkerboard Cichlid Habitat Setup
When setting up an aquarium for the Checkerboard Cichlid, a low water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, driftwood, which can serve as both a hiding place and a dietary supplement, leaf litter or blackwater tannins to replicate their natural soft-water habitat, and dense planting to provide cover, break sightlines, and reduce stress.
Checkerboard Cichlid Compatibility Notes
Classified as mostly peaceful, the Checkerboard Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.
Who Checkerboard Cichlid Is Actually For
Checkerboard Cichlid is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.
The most common mistake is treating Checkerboard Cichlid like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Rio Negro Dwarf Cichlid
Ivanacara adoketa
A stunning but highly aggressive blackwater cichlid from the Rio Negro basin in Brazil. Famous for its striking 'zebra' striping, especially during courtship. They require very soft, highly acidic water to thrive. Despite being categorized sometimes as 'dwarf' cichlids, they possess the temperament of much larger Central American species and are best kept in species-only setups or pairs.
Banded Apistogramma
Apistogramma bitaeniata
A stunning South American dwarf cichlid native to the blackwater streams of the Amazon basin. Known for their distinct dual lateral stripes, they are a bottom-dwelling species that requires soft, acidic water, sandy substrate, and complex environments with caves or leaf litter. They are generally peaceful in a community tank but highly territorial towards other bottom-dwellers, especially when breeding.
Apistogramma Broad-banded
Apistogramma breitbinden
A stunning South American dwarf cichlid from the upper Orinoco basin, formally described in 2011 as Apistogramma megaptera. They are named for the broad, dark band extending across their face. As a blackwater species, they demand warm, soft, highly acidic water to thrive. While generally peaceful in a community setting, they are fiercely territorial substrate-spawners.
Dwarf Flag Cichlid
Laetacara curviceps
A small, colorful, and surprisingly peaceful dwarf cichlid native to the Amazon Basin. Known for their 'smiling' facial markings and iridescent blue/green flanks. Unlike many of their larger cousins, they are excellent community fish, though they may become mildly territorial when breeding.
Black Acara
Cichlasoma bimaculatum
A hardy, adaptable, and robust South American cichlid. They are relatively peaceful compared to larger cichlids but become highly territorial when breeding. Known for their oval-shaped body, greyish-green coloration, and a distinct black mid-lateral spot. They naturally sift through the substrate and require sandy bottoms.
Golden Dwarf Cichlid
Nannacara anomala
A striking South American dwarf cichlid known for its metallic sheen and fascinating behavior. While generally peaceful and excellent for community tanks, they exhibit extreme sexual dimorphism. Females are infamous for becoming hyper-aggressive 'terrors' when guarding eggs or fry, willing to attack fish many times their size.
