I breed Kweichowensis, to be honest....once you have healthy animals established they're not too hard to breed.
I keep 5 adults in a 4 foot x 16 inch tank, roughly half land and half water. The water section is only about 5 inches deep and the land section is rather plain having just a few hides for them.
During the winter the animals will all stay on the land under their hides and the temperature in my newt room will go down to about 58f on the coldest days. They need a good few months at these temps and around march/april time when the temps naturally start to raise you'll find that they become alot more active. As the temps raise to the high 60's fahrenheit usually the males will go to their water section and wait for the ladies. Usually, around 68f ish...the females enter the water. It's at this time that i usually transfer them to another breeder tank. This has three quarters water and a quarter land....the tank i use for this is three feet long x 12 inch wide. The water should also be as deep as your longest newt, and the land section is soil with a hide. Tylototritons generally breed between may/august so during this time your likely (in my experience) to have several spawnings from the newts....9 times out of 10....laid on the soil.
