I have a pair of Spanish Ribbed Newts. They have been courting for quite a while, but no eggs yet. The female is so full, she is double the size of the male. Could it be that she refuses to have the eggs fertilized? Is this dangerous? She has been like this for at least 3 weeks now.

Thanks

Let the water level drop for three or four weeks and then increase the water levels all at once. This will often trigger oviposition.

Thanks Ed,

I did that and it worked, they have been in amplexus for hours at a time trashing around the tank and all, but no eggs. They started the amplexus about 3 weeks ago and last time I observed it is about a week ago, how long does it take for the female to lay once fertilized?

My guess is that the male is not able to position the female to receive the spermatophore. She is really huge. I'll try to post a picture later today.

Sometimes the allowing of the evaporation combined with several water changes within a week period can also trigger the newts to lay.

I keep them pretty close to 70 and they seem to be doing the typical Pleurodeles thing...mating. If I disturb their tank at all or an hour or so after feedings they may be found in amplexus. The female seems to generally lay eggs in the evening or at night, especially when the light is turned off. I'm sorry I can't really offer any advice or suggestions what to do, Patrice, I'm just operating on luck here I guess. It seems like you don't have a problem with courting, just the oviposition. I wish you the best of luck.

P.S. Thanks again for the waltl, Mike http://www.caudata.org/forum/clipart/wink.gif

For my female pleuro it helps to separate her from the others. In a separate tank she'll start laying. If I replace her to early than she will continue in that tank as well.

But generally a sudden water increase with a mild temperature increase (and available plants) should do it. Maybe after a tank cleaning?

good luck
