These newts are aquatic and require an aquarium. 30 gallons can house 2 or 3 newts with enough hides and security. A good substrate is fine sand or coarse gravel too large to swallow. An underwater hide is not neccesary, but provides security. Be sure to get an easy to exit hide, and also one that won't mold (like many cork huts). Remember, the more hides and space that you have, the more newts per aquarium you can have. An acces to water or small floating land area is needed, as paddle-tails do breathe air, coming up for brief gulps. Rocks provide extra shelter, hunting space and decor. Live plants also provide good furnishings and improve water quality. Fake plants are easier to mantain, but do not improve water quality. A flourescent compact light provides full viewing of the aquarium. Temperatures should stay close to 60 F, and no higher than 70 F. Unlike most aquatic newts and salamanders, a powerful filter can be used. This will replicate the newts natural habitat and provide good water quality.
A myriad of food can be fed to these tigers of the water. Tubifex, whiteworms, blood worms and small freshwater shrimp are all suitable. Feeder fish, earthworms, crickets and other foods can all be tried. Some food can be left over for the paddle-tailed newt to hunt later.
You should not handle these newts. If you need to transport them, pick them up in a large net and put them in a water filled bin or moss filled bag. Be sure to quickly perform what ever task neccesary.
Breeding isn't as easy to accomplish as most newts and salamanders. Males in breeding condition have white spots on their tails. Females can lay 40-50 eggs in a breeding season, which stick to the sides or rocks and caves. They should hatch in about 8 weeks and will metamophose in 2-3 weeks if well fed. They will start by needing a mossy land area rather than being aquatic.
