Ambystoma tigrinum

Very cool to see more of these successfully captive raised.
 
Over the last few days the larvae have discovered that chopped earthworm is the best food ever :)
For the first time today, a couple chose to be hand fed :) Since they discovered earthworms, they have had a growth spurt. They are also just starting to darken. The size's are ranging from just over 3'' to an inch.

I noticed today that some are showing a slightly greenish tinge on their sides, and most are getting darker in colour. I also tried introducing them to pellets.... the majority not at all impressed :(. This was to try and make feeding them a little easier while I am away .
The larvae outdoors seem to be growing well, they have now moved onto whiteworm.. super timing as they have just about had all my daphnia. They are also getting some blackworm that I re-discovered in one of my tubs :)

Such cute little guys! Are you planning on separating them so they don't start fighting, or do you have them nice and well-fed so that they can stay together?
 
So far I have not seen any missing body parts, but I will move them into a bigger tub if I do. The smaller larvae do tend to hide amongst the weed, when I feed them they are very flighty... especially if the larger ones get close. Some of the smaller ones have gone missing, but the size difference was huge, I am not keen to raise these.
 
Same here, numbers have dwindled slightly, but I have five or six really healthy looking larvae that are all about the same size. They don't seem to squabble amongst themselves that much, if at all.
I am enjoying raising these as they are so different to my usual Cynops comfort zone. I just keep heaping the chopped nightcrawlers and whiteworms in and they keep hoovering it all up and getting bigger and bigger. I'll post up some more pics soon. :)
Btw, how big do they normally get before they morph?
 
I was wondering about the size they morph at, I think looking back at Hopalong's newly morphed photo it was about 4-5 inches. She gradually got darker and chunkier, the legs got thicker too.
 
I can't take great photos of mine as they live in a scratched plastic tub covered in algae and duckweed. I'm limited to over head shots through the murk, which is a shame as they look like they have nice high tails/dorsal fins. Maybe I need to invest in a glass tank for photographs.:rolleyes:

Here's a few snaps of mine, Mark is a better photographer than me though!

I'm no expert, not even close since I'm only keeping newts, but it seems to me that the animal on the last pic shows some (beginning) traits of a phenotype (cannibalistic morph).

In any case you've did a great job!
 
I know what you're saying, they are all in a 20 gallon at the moment, so maybe it's the overcrowding that's triggering it, it certainly isn't lack of food! There's been no cannibalism since they were very small, but I'm going to split the group up this weekend into some bigger outdoor tubs to be on the safe side.
 
Hmm, after the basics it's not something I know much about. I'm going to read up a bit more on it over the weekend. :)
 
I fished a couple of the larger larvae out this evening so I could take a few photo's. These are just over 5'' now and eating chopped earthworms. The ones outdoors are reaching a whole inch :)

Mine are around the four inch mark at the moment, also on chopped worms and bloodworm. I thought Tylototriton larvae could eat until I got these, they really are eating machines! I imagine they would be even more ravenous if they were stuck in a shrinking pool somewhere.
 
Some are now showing definite signs of morphing. Time to add some land areas :)

    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!
