Adult
Tylototriton kweichowensis are semi-aquatic. Unlike the somewhat "hydrophobic"
Tylototriton shanjing they frequently enter the water to search for food. One breeder I know keeps his adults in a nearly fully aquatic setup with a large island in the middle. A safe maximum temperature for them is probably about 25 degrees Celsius. They tend to be quite active at the warmer end of this range and more aquatic than usual. I would favour the 50/50 water/land approach. They aren't picky eaters and I've found they do well on chopped earthworms and whole waxworms. Adults can reach 25 cm (10 inches) and can eat whole small earthworms or large ones cut in half. A good winter temperature range would be 10-15 degrees Celsius (50 - 59 degrees F) but that is probably only necessary if you intend to breed them - slightly warmer is suitable otherwise. Just like other
Tylototriton they can become quite tame and will readily take food from tweezers once used to captivity. They are not as delicate as
Tylototriton shanjing, though it would be wise to be careful with newly captive individuals. The recent posts of
T. shanjing setups by Mark Naguib and Duncan Buchanan are ideal for
T. kweichowensis too, just be aware that these newts are generally significantly bigger than
T. shanjing.
Good luck.
