The Black Paradisefish is a stunning labyrinth fish native to Southeast Asia, featuring deep black coloration with vibrant red or orange fin accents. These territorial fish are moderately aggressive and require careful tank mate selection, making them suitable for intermediate aquarists. They are hardy, long-lived fish that thrive in planted tanks with adequate hiding spaces.

Care

Diet

Feed high-quality pellets, frozen bloodworms, and small live foods such as daphnia or brine shrimp 2-3 times daily. Supplement with vegetable matter occasionally. Black Paradisefish are opportunistic feeders and will consume small insects and zooplankton in planted tanks.

Behavior

Black Paradisefish are solitary and territorial, especially males, which will aggressively defend their territory. They are labyrinth breathers and must have access to the water surface for air. They are generally active swimmers that explore all tank zones and display elaborate fin displays when establishing dominance.

Breeding

Breeding is moderately difficult and requires a separate breeding tank with dense vegetation. Males build bubble nests and are mouthbrooders; they should be removed after spawning to prevent aggression toward fry. Fry require infusoria and micro foods initially before graduating to larger foods.
