Colours and breeding

In Aquarius a grown male and female breed in a healthy tank. Their young are born about 9 cm long and take after one of the parents.

Now and then a rare mutation shows up: Polka Dot.

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.
