It's been way too long since I started a new thread, so here goes...
H. Cyanurus is a specits I've been interested in for a long time, so when I was offered some juveniles last winter I snapped them up. To start off with I found them quite fragile and tricky to feed. Unfortunately one died and i was worried about the others, but after speaking with another keeper I upped their temperature and things improved straight away. The five survivors are now fully aquatic doing very well, although the males are quite slow growing compared to the females. I'm hoping they will mature in time for next year's breading season and can't wait to see the males breeding colours!

Are they so light or does photo change the colour? I've never seen these live and have just thought the'd be quite similar with cfbn but according to these pics, they are not :)

Until I got these I'd never actually seen them either!
They can go from almost white to very dark with different patterns seemingly at will, especially the females, they look almost ghostly sometimes.
They are quite different to orientalis. I find them much bolder and more active, this strain are also much larger when adult, about the same size as C. pyrrhogaster.

Things are going well in the cyanurus tank. I've recently acquired three more animals so that gives me two males and three females in total which I think is a good number to start with for the breeding project.
They are eating like piggys and growing well, they also seem to be through the delicate juvenile phase and don't really slow down in cooler temps like they did when they were small.
The variation in pattern and colour with these newts still amazes me, especially when the females turn white. If I didn't know better Id swear they were a different species altogether to the males.

Yes she does, but even that appears to vary a little from one week to the next. I don't think I've ever known that in other species!

And where exactly do you keep these individuals? Is this a large aquarium in the house:happy:?

Hi MackMeier, Welcome to the site!
Yes I keep them in an 20 gallon aquarium in the house. I leave it at normal room temperature at this time of year, but use a heater in summer to raise it to around 24/25C as unlike most newts these seem to thrive at higher than normal temps. It's well planted with things like Vallisnria, Ancharis and Java moss and has a small cork island in case they want to rest out of the water.

Thank you very much for the information. What about breeding? If I am not mistaken, then do these individuals breed in small ponds in the spring-summer period (with a peak in May-June)?

Mine haven't bred yet as they are not quite mature, but they should do this year with a bit of luck
Yes they are pond type newts and I believe you are correct about their breeding season in the wild. It seems temperature is quite important to them with peak reproductive activity occurring at 18-27c.

Their habitat is located in the monsoon climate zone, where in summer there is a lot of rainfall, and the water temperature does not rise above 24 ° С. In winter, it drops to 2 ° C.
Water should be of medium hardness. In summer, the water temperature is maintained within 20 ° -24 ° C, and in autumn it is lowered to 10 ° C. Depending on the age and fatness of the animals, they are hibernated for at least 1-3 months. Without winter holidays, they begin to have health problems and weaken reproductive functions.
