Tank & care

Paradise fish doesn't need a group and can be kept singly; choose tankmates to suit its temperament.

Give it at least 60 cm of swimming length and hold the water around 16–26 °C. Match any new species to these ranges before adding them.

Use the stocking calculator to see how many Paradise fish your tank can hold and whether your planned tankmates are compatible — it's anchored to your net water volume and footprint.
