My Paddle tail newts are breeding and i want to know how long does it take them to lay eggs?:confused:
 
I'm not sure, but my P. labiatus pair have exhibited breeding behavior for two years in a row, and no eggs.
 
Courtship is very common, but succesfull mating and eggs are most definitely not.
As always, males are easy....xD
 
I don´t have this species so i can only guess...
I suposse it´s because females require very specific triggers to become able to succesfully breed. Being a stream species they might require some particular factor that scapes most of us.

If i´m not mistaken, most if not all succesful cases (at least to the point of getting eggs) happened in big aquariums. Perhaps satisfying their territorial requirements is a trigger. I expect this species has relatively large territories in their natural habitat.
 
Some days ago i was reading a bit about breeding Pachytritons, just because of curiosity. Erik Keyster and Henk Wallays have succesfully bred them and both of them were overwintering their paddletails in low temperatures. Maybe that's the key?
 
That´s the key for most caudates.I know of many people that overwinter their labiatus at low temps for three months and have no results.
It has to be something else.

Being a stream species, factors such as year-round temperature (perhaps they need constant low temps), annual variations in water levels or perhaps the chemistry of the water, may play important roles.

Out of scientists, i find Erik as the author of best Pachy breedings (he bred labiatus and archospotus) and i don't remember if he wrote anything like changing water levels or it's chemistry, as well he said that temps were changing from 5 to 18'C.
 
By experience I can not say anything because I never tried breeding! But the little knowledge I know the P.labiatus for breeding require extreme conditions. Such as: Huge stone caves and rock, the water temperature of 10cº and a very, very current. With flower pots and plants no one goes there!
Just another opinion! :crazy:
cheers
 
P.labiatus has been succesfully bred in planted aquariums. Plants or their absence don´t appear to have anything to do with succesful breeding in this species.
 
I saw That the female picked up his spermataphores picked up by her cloaca
 
I know that to have a successful breeding with most of the newts do not need their habitat recreated exactly as it is! For most of the plants and rocks that we do not even exist in their habitat! However with this species, there is evidence that this is more than necessary! Now with the power they need, which is not little, I doubt that the plants handle the substrate! Have you thought about it? :crazy:

There is evidence, that it is not....Yahilles posted it. Ian Rigg got eggs in a planted tank with no visible large stones, and the eggs as you can see in the picture were laid inside a flower pot.

I don´t think i understand your point about the plants not handling the substrate....why wouldn´t they? What does a strong current have to do with a plant´s hability to extract nutrients from the water?
 
I give up, you won! :D
Just out of curiosity, Yahilles. these eggs have something? Are adults? What happened to them?

cheers

Those weren´t Ian´s eggs Rodrigo :eek:

Those were Erik´s ones:D. There are a few posts from him here in forum. Search about E. andersoni and P. archoposus CB´s

xDDD Ok, i can see why you think i was referring to the eggs in picture as Ian´s. Perhaps i should have phrased it like "an the eggs, in the same fashion as you can see in that picture, were laid inside a flower pot". :p
 
i think it's a possibility that the females are incredibly choosy in this species ... my females bullied my male so hard he lost the tip of his tail wafting it at them, had an arm removed by one of them, then eventually escaped the tank one night,with three legs and a regrowing stump through the smallest crack imaginable .literally he must have pushed the sliding glass viv lid up and got through the gap... i found him dead and dried up the next day :(
poor fella .. and that was three females and one male in a four foot tank .
