Colours and breeding

• Classic uncommon

In Aquarius a grown male and female breed in a healthy tank. Their young are born about 0.4 cm long and take after one of the parents.

The care values are the ones Aquarius uses, based on how these animals live. Tank mates follow the game's rules: water type, temperature and pH, who can swallow whom, fin nipping, temperament and territory.
