H.cyanurus

[Neonetic]

As above, please share with me your experiences with regards to this species, especially on the typical range of acceptable temperatures, as it is quite hot here.

There may be many different localities and species/subspecies of C. cyanurus. They may vary in their temperature tolerances.

For adults, I would say they can tolerate up to 78F (24C). On the lower end, the adults (but not juveniles) can go down to 56F (13C).

I would generally say what Jen has...but in this case, all of the highland Hypselotriton occur in a relatively narrow range, regardless of species. I suspect that there is more environmental difference among populations of one species than there are between species. That is, they all likely experience more or less the same range of conditions.

Further to that, my fat and happy aquatic adults, of Jen's production, have been living outside for the last couple of months. They're likely if they can average 13C with the cool damp weather we've had since March. On many occasions they have been at or near freezing. The same applies to my H.cf.fudingensis, Laotriton, Pachytriton granulosus, and Paramesotriton chinensis. All are AQUATIC, which limits the extremes of temperature somewhat, but the water bodies are small enough to cool and heat a fair amount, given the chance.

I was thinking that for cooling, I would start with a significant amount of ice to get it to a suitable temperature, and then include some sort of "cooler" by using a bottle that places x amount of cool water at y degrees to maintain the temperature.

Both the tank and the bottle will be insulated. Both variables have to be determined by experimentation on the actual tank set up without newts.

I'm also wondering how different cynops and hypselotriton, amongst non-aggressive specimens, would take to being housed with each other, as they do not appear to be vastly different in size, or habitat.

Thanks!

I think most amphibians can adapt to different temperatures given time and gradual changes, or if they are raised in different conditions to the parents. I suspect that taking H. cyanurus that have been kept under Jen's regimen and exposing them to FrogEye's would not do them very much good unless they had a few months of gradual lowering to adjust.

That said, a friend of mine had losses of H. cyanurus (the 'European pet trade' form) until he added a heater during winter months...

I should note that both my Hypselotritons spent the winter in water in the lower level of the house, which is rather chilly. They spent the previous summer and fall outdoors, until prolonged freezes were a risk. Obviously Chris is right - it's generally a bad idea to make a drastic temperature change, regardless of what a species' tolerances are.

 

[Neonetic]

So I would be safe to say that it is more advisable to keep Hypselotriton's at 25 celsius here, since they stick around for sale at 27-30 celsius? Basically, what makes more sense, keeping them at 25 long term, or gradual cooling to under 24 and then long term keeping?

I'm not too sure how this comes down to a suitable range of temperatures, just some brief idea of what I'm referring to.

 

[Neonetic]

The question is really, do newts have a suitable range of temperatures, or can this range be edited slightly through generations of breeding?
