does anyone have any experience breeding this species? is it similiar to breeding T. granulosa? the ones i am curently keeping are in the terrestrial stage, is a transition period or heavy misting period required to induce breeding or is simply having a large land and water portion enough? i have observed them breeding in the wild but captive breeding is a whole different story. would love to have some juvies to share with other east coast hobbyists. any help at all would be greatly appreciated!
 
Please use adequate capitalization...it makes it much easier to read.
 
I would assume their breeding requirements are similar to granulosa. For grannies some people keep the adults terrestrial then just plop them in a tank full of water when they want to try and breed them. This has worked quite well for one particular member. T. torosa are so rarily kept much less captive bred that I think your just going to have to experiment and see what you can come up with.

Do you ever post something positive, when someone asks a question? :rolleyes:

Yes, i definitely think so.
And excuse me for trying to do my share of the job as a moderator. Enforcing the forum rules happens to be part of it.
I happen to think that remembering users to use adequate capitalization is positive, if not for the particular user, for the forum.
 
For anyone who had difficulty reading my above post, here it is once again with the requested changes:

For everyone else, thanks for your constructive replies!
 
A quick update:

I put the newts in an aquatic set up with a small land area and they have not left the water since. Both have seem both males attempting amplexus with the female but she is not very receptive. The smaller of the two males (about 5") dropped a spermatophore but I have not seen the female pick it up. Hopefully she will warm up to their advances!
 
Hi,

are you shure you have T.t.torosa?

In the shops you normally get only T. gran. even if they sell them as torosa.

Greetings

Uwe -

They are wildcaught from an area where T. granulosa are fairly rare, i am 90% sure they are T. torosa (i do not feel like inspecting vomerine teeth). The female, who was caught in a different county looks like a granulosa though, so my trio is 2 male torosa and 1 granulosa. I may end up releasing her soon as she is not aclimating as well as the males.
 
Hi,

you don´t need to check the teeth, you can go for the diffense posture (see Petranka) to distinguish the two species. Interbreeding as it may be does not make much sense to me.

If she is a torosa, you just have to wait til she is responsive and not just release here.

As I see you are from the East coast, which is far away from the natural habitats of this species.

Don´t release her!
She has been in contact with caudates of a different origin....she might be carrying patogens that could potentially cause a lot of problems in her habitat.
 
Definitely do not release her. Not only is she more than likely carryng pathogens that can be spread to native wildlife but it is also against the law. I'm right here in VA and will be more than glad to pay for shipping if you have to get rid of it but please don't release into the wild.
 
Im looking for a large female T. granulosa and would be willing to pay for shipping. Then you would not be riddled with guilt for releasing her.

oops Greatwthunter called it first........
 
I am from California, recently moved to Maryland. I am currently working on building a larger tank for them that will include a large (12"x12") planted land area. I am hoping this will improve her condition. She is still active and eating. I have not seen any Petranka posture (or ever observed this in the wild). her different coloration may be due to the abundance of scuds in the pond she was found in. If I posted pictures would anyone be able to do confirm whether she is torosa or granulosa?

They were only caught 10 miles from eachother so I highly doubt that they would be carriers of significantly different pathogens. Either way, release is no longer the plan.

You would be very surprised what a difference 10 miles can be. Specialy for a small animal.
 
Quick update; all the newts are doing well in their new tank (a 20gal long). 60% is a planted 9" deep water area with thin sand substrate and the rest is cocoa fiber with clay balls underneath with a driftwood "ramp". Sphagnum moss and possibly some ferns will be added later. I have not seen anymore breeding behavior which is fine since they are different species, but all appear happy and healthy. Thanks to everyone who replied.
