Triturus dobrogicus larvae

nice video Jake! they look great and some how seem familar. Good luck with them.
 
Well, at just over 3 months old this group has grown quite a bit, some of the males have crests, some don't. Here is the same batch feeding now on chopped nightcrawlers.

Looks great Jake, I know T. dobrogicus grew fast, but I've never seen them grow this fast! What do you feed your worms, fertilizer? haha
 
O_O
Three months???? They have crests and look like that in just three months?????? Ok....i´m doing something really wrong...
 
My mistake.... that's 3 months since the last video. In the last one they were about 1-1.5 inches long, I can't remember how old they were at the time, but they may have already been 2 months old. I do make sure to feed them as much as they'll possibly eat though.
 
Still.....5 months...it´s nuts!
My male won´t grow a crest, it´s rather frustrating xD
Congratulations Jake, wonderful job.
 
Awesome newts Jake! If some of them a cresting then can they mate at this age? I've heard they sexually mature at 2 years right?

It's been about 60 degrees down there lately.

They have very nice crests for their age, but I'm sure they're still too young to breed, but we'll see.
 
Wonder if it is an artifact of them being kept permanently aquatic? Interesting stuff!

Do dobros normally go terrestrial?
 
My T. dobrogicus have bred in their first year. Don't expect a lot of eggs, but it is certainly possible.
 
Can i ask you, Coen and Jake, how you keep your animals? what size a tank, what temps year round, etc....
My male won´t go into breeding condition, it´s very deceiving.....
Sorry for the change of topic.
 
Hey Rodrigo! I have a young male T.Dobrogicus that is starting to crest as well. He's changing color and his crest is rising everyday now. I'm not saying this to tease you at all, for real I'm not. I started to feed mine less and not as much but didn't starve him. I did this for a short period of time, like a month or two. Not to mention I kept him in a room about 60 degrees. After that short period I moved him to a room with slightly higher temperatures and increased food source and kept him with females.

I keep this group in a 30 gallon tank now, and some of their sibblings (raised by a friend) are in 10 gallon tanks. During the summer the newt room was a pretty constant 67-68 degrees F. Lately I've been leaving the window down there completely open to let in a lot of cool air from outside. I checked the temperature yesterday in there and it was 56 degrees F. I am almost positive that's why their crests grew so much so fast, that and a few good cool water changes.

I've noticed my marm and karelinii juvies cresting in the first year as well.
 
This is my first year in my own house, where I have a separate room to keep the newts. I also keep a window open to let it cool down this winter. Back when I lived with my parents, they just went into breeding condition every now and then, no special things going on with temperatures. If I saw a male going into breeding condition, and I'd want to stimulate it, I'd do lots of cold water changes like Jake mentioned, this really does help.

How large are the male's crests now? Will you try to breed them?

A couple of the males have full crests. Some of their crests lowered this past week because the weather got pretty warm again (I just love Illinois! jk).

I'm not going to try to breed them, it just happens with the temperature change during the winter.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!

    Dear All, I would appreciate some help identifying P. waltl disease and treatment. We received newts from Europe early November and a few maybe 3/70 had what it looked like lesions under the legs- at that time we thought maybe it was the stress of travel- now we think they probably had "red leg syndrome" (see picture). However a few weeks later other newts started to develop skin lesions (picture enclosed). The sender recommended to use sulfamerazine and we have treated them 2x and we are not sure they are all recovering. Does anyone have any experience with P. waltl diseases and could give some input on this? Any input would be greatly appreciated! Thank you.
