Yes, I mean to say I have four newts. Here’s a brief description of how I’ve kept them in the hope that they breed:
I kept them for the summer at about 70-73, and starting in October I gradually lowered the temperature in their 3/4 land, 1/4 water setup until it got to about 45 degrees in January. In December, I increased their water level to about 6 inches from the previous 2. Once the temperatures Had got to about 50 degrees (which happened after I had increased the water level) 2 of the newts entered the water (I believe these to be male). The newts were in my basement, and the coldest I had been able to get them was 45 until one day when it hit 40. Thats when the other 2 newts entered the water. But I knew It was not going to stay 40 in the basement, so I bought a fridge, set up an entirely aquatic setup with a turtle dock, and set the temperature of the fridge to 40 degrees. Simultaneously, I have decreased their light cycle from 14 hours down to 10 in January, and now I am increasing the light cycle once more.
All the newts have stayed in the water since being moved to their aquatic setup, and the one newt I am sure is a female looks to be swollen with eggs, while the one newt I am sure is a male has developed a slightly flatter tail and more pronounced cloaca.
Information I have gathered says that they need a good 2 months of 40 or so degrees in the water and that the males bulk up and develop their massive tails in the spring, and then proceed to breed.
