Care at a glance
The paradise fish from East Asia was one of the first tropical ornamental fish kept in Europe, long before aquarium heaters existed. It is remarkably cold-tolerant and colours up beautifully with blue-and-red barring and broad, flowing fins.
It is a labyrinth fish that gulps air at the surface, so always leave an air gap under the lid, and keep it covered because it jumps. Males will not tolerate each other and are also hard on other colourful, long-finned fish, so keep a single male and choose the rest of the community with care.
