T. marm eggs hatching

[ellroy]

Hi,

I thought I'd post a pic of my first ever newt larva from one of Morg's T.marm eggs. You can see the second one getting ready to roll out to the left of the pic. I'm looking forward to seeing them develop and am poised to start hatching brine shrimp over the next few days. As far as I can tell there are at least another 3 which will hatch shortly, I'm no expert but I am basing this on the black lines I can see through the folded leaf.

I'll post more as they develop if people are interested!

Cheers

Alan

Once the black lines along the back become intense, they hatch rather quickly (unlike for example Cynops sp. which stay in for longer).
Are those bubbles because of the chlorine of tap water? I´m only asking cause it looks like that, and that´s something you really should avoid since chlorine is toxic for them.

Good luck raising them, they are a brilliant species. The larvae of Triturus are very fun to raise

Congratulations. Last year I had some of Morgs eggs and I ended up with 5. I have really enjoyed raising these, and I am resisting the temptation to raise more. I am looking forward to seeing more.

No, I am using rain water so there shouldn't be any chlorine? Is rain water a risk? I was conscious of avoiding chlorine and thought that rain water would be pretty pure....am I being naieve??

I am dechlorinating some tap water which I will use for a water change tomorrow.

Thanks for your input,

Alan

Oh, allright, i just thought it could have been, you know, because when you have chlorine in the water you get bubbles on the surfaces too.
Rain water is too low on minerals. Aged, or dechlorinated tap-water should be perfectly fine. You can also use spring water.

 

[ellroy]

Thats great Azhael, thanks for that. When you say spring water are you referring to bottled spring water or water from a natural spring??

Cheers

Just a correction on this: Tap water, even dechlorinated its not recomendable. Last year I´ve done that to my T.marm and C. orientalis and had many losses. The chlorine remove I used its the best on the market (Tetra aquasafe), so I know perfectly what I am talking of.
Also I must tell like it was told, that rain water is mineral-less making pH give a great drop to 5´s. I think aged its the best at all, and its what I use for raising my baby newts.
Greetz,

Thanks jorge. how long should water stand before it has aged enough?

I dechlorinated a watering can full of water ( dedicated to axolotl/ newts etc) and used this over a number of days. I did @80% daily water changes and fed twice daily. I raised them till they morphed in a shoe box sized lidded plastic box.

Maybe your water has chloramine and your dechlorinating product doesn´t get rid of that. Dechlorinated water is widely used in the hobby, many many users in this forum use it and there are no problems so long as you use it properly and there is no chloramine in your water (unless your dechlorinator has also thought of that).
I don´t use any dechlorinator, i simply let the tap water sit for 24 hours and never had any problem....tap water is most certainly usable.

You know, mainly problem in tap water for Caudate larvae is, in fact, the great presence of gases, rather than any other cause. Oxygen and Nitrogen that were not dissoluted in water but rather forced to do it. Pipes, Pitching engine systems, sewer systems, all of those make atmospheric gases to be unsuccessfully incorporated in water. If you let a bowl of water for a few days on a table, the gases they will go out with no problems, but in presence of living beings like small caudate larvae, the water their body uses all the time to bio-synthesis, will create bubbles in digestive track, making them lose pitch control of their body and soon perish...
Of course all haves to do with our Tap water. Over here, water for consumption comes from mountain streams that are then treated and purified. But in fact, even being very good quality water, almost absent in chlorine, Its obviously transported in pipes and sent to higher points by some engines witch all contributes to the presence of these gases in water. Old Tap water is good in fact. I would not risk less than 2 days at least. 24h didn't worked well here. Its a question of each of us try and discover what the best method according to our ideas...
Just wanted to share my disgraces in order to avoid others to commit the same!
Hope you do well with those little fellas ellroy:happy:

Cheers,
Jorge

Thanks for all the information guys, very helpful.

I now have six of these little guys and the first ones are already noticably bigger. I am still feeding them newly hatched brine shrimp but at their current size I imagine they could handle bigger prey? Any suggestions?

Cheers

Alan

Daphnia! xD
Sorry i´ve recently started culturing it and i´m hooked
You can also feed them copepods, microworms, and as they gain size, you can "train" them to accept frozen bloodworms.

Thought i'd post a recent photo. They seem to be developing well on the newly hatched brine shrimp
