Macropodus opercularis, or Paradise Fish, was one of the first tropical species introduced to the aquarium trade. Native to Asia, it is renowned for its magnificent blue and red reflections and its great resistance to temperature variations. It's an ideal fish for beginners looking for a colourful, lively aquarium.

1. Behaviour & maintenance

Lively, curious and sometimes territorial, especially between adult males. It should be kept in an aquarium of at least 100 litres, with plenty of natural plants and hiding places. Prefers slow-moving water and calm areas at the surface for building its bubble nest.

2. Water parameters

• Temperature: 18-26°C
• pH: 6.5-7.8
• GH: 5-15 °dGH
• KH: 3-10 °KH
• Minimum volume: 100 L for a couple

3. Diet

Omnivorous to carnivorous: flakes, pellets, artemia, bloodworms, daphnia and aquatic insects. Find out more about our foods for tropical fish.

5. Reproduction

Easy: the male builds a nest of bubbles on the surface. After spawning, he protects the eggs and fry. Ideal temperature: 24-26°C. The young quickly accept artemia worms and nauplii.

6. Compatibility

Keep alone, in pairs or with calm, medium-sized fish (golden barbs, tanichthys, danios). Avoid long-finned fish or males of the same species in a small area.

7. Shipping, delivery & transport points

The fish are shipped in professional isothermal packaging to ensure the safety and well-being of the animals during transport.
