斑点双缨丽鱼 · Spadetailed Checkerboard Cichlid

Overview

The uncommon checkerboard cichlid Dicrossus maculatus is a demanding breeding project. Very soft, strongly acidic water is important for egg development, while the female's fin signals make brood care particularly engaging to observe.

Distribution & habitat

It originates in Brazil's Amazon basin, including the Tapajos and Maues rivers and neighboring waters.

Aquarium setup

Use substantial planting and numerous sheltered cavities with small entrances. Maintain the soft acidic conditions consistently and give water quality particular attention during reproduction. Cover should offer genuine retreats from disturbance rather than merely decorating an open tank.

Diet & feeding

Rotate good frozen foods for routine meals. Live foods may be important when bringing adults into breeding condition, so a single frozen item should not be assumed adequate for every stage.

Behaviour & compatibility

Its peaceful disposition is specifically described toward other species; this does not establish universal tolerance of conspecifics. Small shoaling companions have reportedly improved parental care during breeding, an observation to consider cautiously in an otherwise suitable setup.

Sexual dimorphism

Size is unreliable: females can match or exceed males. Males generally display stronger colors, including a striking blue sheen across the sides of the head and gill covers, while females look more subdued.

Breeding

Eggs require exceptionally soft acidic water, and maintaining cleanliness remains essential under those conditions. Brooding females develop bright yellow pelvic fins and use them to direct the young. Spreading these fins draws the fry closer; folding them signals a stop. The brood is often guided into shelter before nightfall. A female still caring for young may not reproduce successfully again until that brood has been separated from the adults.
