Dicrossus maculatus 1–2 cm | Checkerboard Cichlid

Overview

Dicrossus maculatus, often sold as the Checkerboard Cichlid, is a beautifully patterned dwarf cichlid from South America that rewards the aquarist with subtle colour, fascinating behaviour and a genuinely peaceful nature. At just 1–2 cm on offer, these are young fish that will grow into elegant adults best kept in a carefully maintained, soft-water aquarium. Their delicate markings and calm temperament make them a superb choice for experienced hobbyists looking for something a little different from the usual community fish.

Unlike many cichlids, Dicrossus maculatus is not a boisterous species. It is best appreciated in a quiet, mature setup with gentle tank mates and plenty of cover. When kept correctly, it becomes an engaging fish to observe, especially during feeding and courtship. We recommend this species for aquarists who can provide stable water conditions and a naturalistic environment. As with all live stock, we offer live arrival guarantee and fast UK delivery for a smooth, reliable experience.

Because these fish are small and still developing, they should be acclimatised carefully and housed in a well-established aquarium. Their long-term success depends on soft, acidic water, low stress, and a varied diet of small meaty foods. In return, you get one of the most attractive dwarf cichlids available in the hobby.

Care at a Glance

Origin & Natural Habitat

Dicrossus maculatus originates from slow-moving freshwater systems in tropical South America, where it inhabits blackwater and soft-water environments associated with leaf litter, submerged roots and fine vegetation. These habitats are typically shaded, low in mineral content and rich in tannins, creating the subdued conditions this species prefers. In nature, the fish uses cover and dappled light to stay secure while foraging for tiny invertebrates and other microfoods.

This background is important when planning aquarium care. The species is adapted to warm, clean, very soft water and does not appreciate hard, alkaline conditions. A mature aquarium with natural décor will help reduce stress and encourage natural behaviour. Dim lighting, botanical elements and a calm tank community all contribute to success.

Tank Setup & Water Parameters

For best results, keep Dicrossus maculatus in a mature aquarium with fine sand or a very smooth substrate, driftwood, leaf litter and dense planting. Floating plants can help diffuse light and create the shaded, secure feel these fish enjoy. Caves, root tangles and visual barriers are useful, particularly if keeping a pair or small group. The species is small, but it still benefits from a tank that offers territory and retreat spaces.

Water quality should be excellent and stable. Aim for a temperature of 24–28°C, with a pH between 5.0 and 6.8. Soft water is strongly preferred, and regular maintenance is essential. Small, frequent water changes are better than large, infrequent ones, especially in a planted or blackwater-style setup. Avoid strong currents; gentle filtration is ideal, as this species comes from calmer waters and can be stressed by excessive flow.

Because these fish are sensitive to poor conditions, we recommend adding them only to an aquarium that has fully cycled and matured biologically. A secure lid is also sensible, as cichlids can be startled and may jump. If you are creating a biotope-style aquarium, think leaf litter, subdued lighting, and natural wood tones rather than bright open spaces.

Feeding Guide

Dicrossus maculatus is a micro-predatory omnivore that does best on a varied diet of suitably sized foods. Offer high-quality frozen and live foods such as baby brine shrimp, daphnia, cyclops, grindal worms and other tiny invertebrate foods. Good-quality micro pellets or crushed cichlid granules can also be accepted once the fish are settled, but these should complement, not replace, meaty fare.

Feed small amounts once or twice daily, ensuring all food is consumed quickly. Overfeeding can pollute the water and may lead to digestive issues. Variety is key: a mixed diet supports colour, condition and breeding readiness. For newly introduced fish, live or frozen foods are often the best way to encourage feeding.

Tank Mates / Compatibility

This species is peaceful and best kept with other calm fish that will not outcompete it for food or intimidate it. Suitable companions include small tetras, pencilfish, hatchetfish, Corydoras, Otocinclus and other gentle South American species that enjoy similar soft-water conditions. If you keep a pair, provide plenty of cover and avoid overcrowding.

It is not a good choice for aggressive cichlids, fin-nippers, large boisterous community fish or species that prefer hard, alkaline water. Fast feeders can also be problematic, as Dicrossus maculatus is a deliberate feeder and may struggle to compete. In mixed communities, ensure food reaches the fish and that there are enough hiding places for all occupants.

Breeding pairs may become territorial around spawning sites, so extra caution is needed if you intend to breed them. In a community setting, the best results come from keeping them with quiet, compatible species in a spacious, well-structured aquarium.
