Quick facts about Paradise Fish

How Many Paradise Fish Should You Keep?
Paradise fish are usually kept singly, as pairs, or in carefully managed groups.
- A single male makes an excellent centrepiece fish
- Pairs can work in larger planted aquariums
- Multiple males generally require substantial space and visual barriers
Keeping too many males together can lead to:
- Territorial aggression
- Fin damage
- Stress and chasing behaviour
They are often more aggressive than gouramis but less aggressive than male bettas.
Ideal Tank Conditions for Paradise Fish
Providing the right environment helps paradise fish display their best colours and behaviour.
- Tank Setup: Well-planted aquarium with open swimming space
- Substrate: Sand or gravel substrate
- Plants & Decor: Dense planting, driftwood, floating plants, and hiding places
- Water Conditions: Stable freshwater with moderate hardness
- Filtration & Flow: Gentle to moderate filtration
- Lighting: Moderate lighting
As labyrinth fish, they need access to the water surface for breathing atmospheric air.
Compatibility with Other Fish
Paradise fish can work in carefully planned community aquariums.
- Good Tankmates: larger tetras, rainbowfish, corydoras catfish, weather loaches, and peaceful barbs
- Avoid: bettas, guppies, long-finned fish, and highly aggressive cichlids
Their territorial nature means tankmate selection is important.
