Macropodus chinensis – Chinese (Round-tailed) Paradise Fish (~6 cm)

A graceful labyrinth fish with a round tail (unlike the forked one of typical Paradise Fish). It displays subtle, natural hues—bands of muted blue-green and soft oranges—becoming more vibrant during courtship. Males grow slightly larger and more colorful than females.

Tank Setup:

• Minimum length: ~60–100 cm (about 60–100 L) for a pair

• Pale gravel or bare bottom and dense planting

• Floating plants or driftwood to simulate peaceful, shaded habitats

• Secure lid essential: excellent jumpers

Water Conditions:

• Temperature: 16–26 °C, can handle cooler periods (even down to 10 °C in some strains)  

• pH: 6.0–8.0

• Hardness: soft to moderate, around 3–15 °dH (≈5–19 dGH)  

Diet:
Omnivorous—eats high-protein foods like live or frozen brine shrimp, daphnia, insect larvae, worms, plus flakes or pellets. Feeding once or twice daily keeps them healthy and colorful.  

Behavior & Tankmates:

• Can be kept in peaceful community setups

• Males become territorial during breeding—better housed singly or as a pair

• Suitable tankmates include peaceful medium or large species that won't be harassed  

Breeding:
Bubble-nest builder: the male builds a foam nest among surface cover and courts the female. After spawning, he guards the fry until they hatch and become free-swimming (usually within a few days).  

Hardiness:
Quite hardy and accommodating of wide water conditions. This includes unheated tanks and even outdoor ponds in cooler climates.
