Water parameters
Overview
The black paradise fish is the dark-colored relative of the well-known paradise fish. The males' body varies from dark brown to black; they have long dorsal and anal fins and a forked tail with extended tips. In the hobby it was long known as Macropodus concolor, and this name is still common. Its natural range is not known for certain. It is calmer than the paradise fish and likes slightly warmer water.
Tank Setup
- At least 60 liters for a pair.
- 22–25°C, pH 6–7.5; soft to moderately hard water.
- Dense plants, floating plants and hiding places for the females.
- Gentle flow and a tight lid; warm air above the surface.
Diet
Mainly carnivorous. It accepts flakes and granules; supplement with frozen and live bloodworms, brine shrimp, daphnia and mosquito larvae. Feed in moderation 1–2 times a day.
Behavior and Compatibility
More docile than the paradise fish, but males are territorial toward each other. It hunts shrimp and fish fry; it may harass slow, long-finned fish.
Good companions: robust, calm fish of similar size: zebra danio, rosy barb, large rasboras, corydoras.
Avoid: dwarf shrimp, slow long-finned species (bettas, guppies), very small fish, a second male of its own species (in a small aquarium).
