These amphibians live very well in an aquarium of suitable capacity^ 

 30 to 40 liters of water for each pair. This water should be renewed 

 about once a fortnight. Some clusters of aquatic plants {Elodca cana- 

 densis) will assist in maintaining- the purity of the water, and their top- 

 most branches will serve, at the same time, as a support for the eggs 

 deposited by the female. These eggs resemble frogs' eggs; they are 

 covered with a similar viscous material and are deposited in strings 

 instead of being agglomerated ; they hatch in from 15 days to 3 weeks, 

 depending upon the temperature of the water.
