Oh no that's terrible! I wonder if it would be worth trying them in a terrestrial setup, at least it would rule out something in their water?

I´m really sorry to hear that, Julia :S
It does sound superficially like some kind of poisoning, but i have no idea what the source might be. The worms seem unlikely.
I hope moving the animals to a new enclosure makes the deaths stop.

Is there anything in the tank that´s new or that could be leaching metals or whatever?

Nothing was new in the tank since they were first placed there, it had sand, plants and slate and stones. The tank had been used in the past for raising various eggs, but cleaned after each use. I am at a loss to know what happened. I am a little suspicious that this occurred after they were fed, but none of my other animals are showing any problems.
The two healthier ones are in a more terrestrial set up, they are both sat in a small water bowl.

I am so sorry about your losses. I know what it feels like when it seems you do everything "right" and then there is "unexplained" loss. I, also have raised Taricha granulosa, and I have experienced all the challenges of raising them from eggs. Though I have had some success raising a few to adulthood, I also have had some"unexplained" losses along the way. One thought that comes to mind: hidden disease in the tank. Sometimes, even the cleanest tanks can carry disease and bacterial colonies hidden in the plants and rocks that can transfer to cleanly added water again ( if rocks etc are not cleaned also ). I have had fish epidemics spread this way. Also, another thought: your juveniles might be going through life-cycle related changes in their needs. I just know,my juvenile Taricha seem to really want to become "land phase" after metamorphasis. I have tried keeping them aquatic... but they seem to really "want" to get out of water and live in rocks and leaves ( they try to climb on up everything!). Their skin gets really rough and bumpy like their hormonal state is "pulling them" to the land. However, later in life, (about 18 to 24 months old ) my Taricha seem to accept being aquatic again. ( I always like this because aquatic is an easier set-up!) Anyway, I just wonder if your juvenile Taricha might thrive better in a land set-up for now? Just some thoughts...

Please know I am rooting for you and your little guys! ( I love the species)

As said above, its always awfull losing animals, and especially when the cause is not known.
I had a problem last year with newts dying for unknown reasons, and with no signs of anything wrong with them.
A very distressing time for me and I, more than once thought of stopping keeping amphibians all alltogether.
My Cyclone then pointed out Bactyfec from here
Fertilisers & Feeds Price List

I used it, and the deaths stopped.
With not knowing what was causing the deaths,I dont know if it was definatelly the Bactyfec,, or if the deaths would have stopped anyway, but it may be worth trying?

Do you think they could have picked up a pathogen that is being harmlessly carried by another species you keep?

Thanks for your your comments, they are very much appreciated.
It has been rather a frustrating and sad time, it is the not knowing what has gone so wrong that I find very hard to deal with. This seems to have affected the largest animals first so maybe it was something to do with them needing a terrestrial phase, they did have a land area to go onto to they chose to spend time more aquatic. I also wonder if there had been something in the worms that maybe built up over a period of time, that may explain why the largest died first.
Visually the bodies looked generally fine, maybe a little pale. The eyes looked a little swollen prior to death. There was no other swellings or discharges from any of them.
I have considered this may be a pathogen that has been transferred to them by another species. I do use a set of 'tools' just for them, but maybe that was not enough.
This morning I still have three survivors. They are in a more terrestrial set up with a water bowl and leaves to hide under. I have added lots of white worm as I am loathe to use the current supply of earthworm. I have everything crossed with the hope these last three survive.

Sorry to hear this and good luck with the final 3, as you know I had some die last year, I think mine were due to a soil substrate gone bad and now understand the attraction of bare-bottomed tanks.

I'm very sorry to hear about your losses!
I raise granulosa every year and my experiences are almost the same as Jane has described above. It is possible to have unexpected losses in every stage of rising them and they stay terrestrial for about 18 to 24 month. I was quite surprised as Patrick told me his stayed aquatic (I've seen the animals in Gersfeld, they were much bigger than my terrestrial raised of same age). I've tried to get granulosa juvies back to water early and it always leads to the death of the animals, but it wasn't as you described, mine always wanted to leave the water and refused food most of the time, after a while they started to devellop skin problems, if this happens there is no chance to save them even in a terrestrial setup. But they never died as fast as you described.

So I can't tell any reason for your losses, but I think giving them a more terrestrial setup is a good chance. Has their skin changed since they are terrestrial? Skin problems often start at the tip of tail are those ok with your animals? Have you really seen them eating the earthworms you were feeding them?

Just some thoughts, I hope the remaining three will make it!

I lost another yesterday and I am pretty sure the other two won't live. I added Bactyfec to their water this morning, but I fear it is too late.

After your comments Fabian, I took a closer look. Right away I could see one has swollen eyes. Looking closer it has a pale discolouration around it's nose and a patch of similar mid tail. The second has similar.

With regards to the earthworms, they had fed on small cut up earthworms for over a month. previously it had been daphnia and whiteworm.

I still have two survivors and they have improved a little.

When the last one died I noticed the other two had swollen eyes so I had expected them to die too. One became very pale and seemed to have fluid inside its belly. I returned them to their medicated water bowl as often as I could. Friday night I was horrified when I saw one that seemed to have a massive ulcer developing along its back, I decided to leave it for 24 hours to see what would happen, but there was no change in appearance. The following 24 hours it shed its skin and visually it looks a lot better, but maybe a little pale still.

Thank you to everyone who offered advice, it has been very much appreciated.

How are the two survivors doing? I really hope they've pulled through.

The two survivors are merrily stomping around their little tub looking healthily plump and both are eating well:D I am feeling a lot more optimistic now and shall move them from their current set up to a soil based one at the weekend.
All the other caudates seem fit and well so hopefully whatever the illness was remained contained.

The symptoms sounds like a Protozoan infection. I would treat with Metronidazole, you can find this as a fish medication for hole- in the-head disease. Hexamita ovatus, Karotomorpha swezyi, and Tritrichomonas augusta are common in this salamander.

They look like they're out of the woods now, don't they? To me their body/head shapes look slightly different, It would be a kinda happy ending if you have a pair, wouldn't it? :)

They have now been moved onto a soil based set up. They spent the first hour or so delicately tip toeing through the moss but have now settled. They become quite spoiled now and are tweezer fed.

  • AMurry24537:
    0 nitrates doesn't sound dangerous, but it does sound very unlikely if the tank is fully cycled. Are you positive you're performing the test correctly? If you're using the API one, that is by far the trickiest test to do right. If the reading is correct, I would guess that either your tank is not cycled, you just did like a 100% water change, or that you have plants sucking up the nitrates, but even those shouldn't leave you with 0.

    Unlike
  • Dragonfire:
    0 is fine unless the tank isn't cycled. Most tanks definitely won't run at 0, but I've had fast growing emergent plants drop nutrients so low that other plants like floaters were choked out and began dying so it isn't impossible. Some less sensitive kits may read 0 but they are just not precise enough to give an accurate low level reading too.

    Hey guys! I’m having an issue with my filter and was hoping for some suggestions. I use an aqua clear 20-50 gallon filter for my 20 gallon axolotl tank. It has worked great since I got it back in December! Recently though, I’ve noticed the flow of the water has turned into more of an intense trickle than a constant flow (if that makes any sense?) I thought it may be something was stuck in the filter or maybe the sponge needed to be swished around in tank water, so I did both of these and it still trickles. It’s a very strong trickle, so the tank is still getting good filtration. It is just so loud and I was wondering if this has happened to anyone else and if there’s a way to fix it?

  • AMurry24537:
    Hmm, I don't know much about those filters, and I'm having trouble picturing what you mean, but could it be simply that your filtration media is arranged in a different way? Or maybe you're losing water content to evaporation? Just throwing out ideas. 😁 Again, I don't really know much about that kind of filter

    Hello all. My male axolotl's cloaca hasn't been looking quite right for 13 days. When I first noticed it, I immediately checked the temperature of his tank and it was around 70-71. Way too warm for him, so I took him out and have had him tubbed in the basement ever since. The temperature of his water is now 64-65. The issue seems to be that one 'half' of his cloaca is flared out and has white fuzzy stuff on it. It almost looks like a bunch of little white spikes of hair. Only one half is this way. Sometimes said half is flared out almost all the way, and other times it's almost completely back inside of him. I had him in tea baths overnight for probably five days, and then a solid 24 hours of mild tea for around three days. I don't remember exactly, my apologies.

  • CrazyForLotls:
    Since it was looking better (not flared out so I couldn't tell if it was still fuzzy) I put him back in plain, dechlorinated water. He gets daily water changes, always dechlorinated. The tea I used was plain black tea. The brand was Lipton and it came in a large box, purchased from the grocery store. Does anybody know what this could be? I found a couple old threads with a similar issue, but nobody ever replied to them. I can post a thread if you'd like some pictures, but they aren't very good. My camera was having trouble focusing and my axolotl kept moving.
