Hi all,

First time posting here.

I recently hatched 50 eggs from our pair of axolotls about a month ago (I work at a school and our Biology department wanted a pair, also going to donate some to friends and colleagues if enough survive), but I'm a little concerned as none of them have developed legs. They've definitely grown (about 2.5cm or so now) and are eating and swimming, but I was expecting them to have developed at least the front legs by now - is this normal?

Ello! Can we see photos of them?

they should have started growing their front legs after about one week. and their back legs within about 2-3 weeks.
it is very strange that they haven't grown yet. if you got the parents from a breeder ask them how long it took for them to grow their legs. it could be a genetic malfunction. are they imbred babies. what is their diet?

Could be a developmental problem, but all the 50 babies from a couple of normal parents ... I seriously doubt.

If the gills are very well developed, then the fore legs (very thin when young) could be confused with them.

At 2,5 cm long, they can begin with cannibalistic trends (especially in case of overcrowding but I don't know anything of your setup). Then most of then would lack legs but a few of them could still have them.


I suggest you to try to observe them by their side. If you see the head lying on the floor of the tank, then they really lack fore limbs.
Otherwise if you see their head frankly above the floor, then they probably have something to sustain the head (no balancers in this species and other of this group)

Hi all,

Thanks for your help!

I've attached a couple of pictures, I didn't do this on the first post because (as you can see) my phone camera is pretty low quality so I'm not sure how helpful they'll be.


Diet: daphnia, so many daphnia. They eat the juveniles at about as quick of a rate as my colony of daphnia can reproduce - I've set up a second colony so I can feed them from each on a rotation.

Set-up: they're in 3s in c1 litre of water, I also have a few in very small 100ml tubs for a few days at a time if they look like they're not eating, then after a few days, when I can see they've eaten, I move them back to the more spacious tubs. I've not observed any cannibalism, and think they've got enough room not to get in each other's way much, but obviously I'm not there 24/7 so maybe.

Hereditary issues: my fiancée got our pair from an aquarium, given that we only found out they weren't both males when one laid eggs, I wouldn't rule out them being siblings.

    Does anyone know if aquacare general tonic is ok for axolotls as a treatment for bacterial or fungal infection?

    Hi Lilith, you can check the medications page for a list of axolotl safe treatments. Although if the infection is mild, I would stick with fridge and salt baths!

  • faebugz:
    I believe the fridge gets to about 54°, so if you can replicate that in the tank, it might be okay. I personally would fridge just to make catching them easier, and if the infection is something in the water column at all, it will hopefully die out while they're AWOL (I'm thinking like ich for fish, not sure if axies have an equivalent)

    My three inch axolotl was having trouble pooping up to a few days ago. I wasn't feeding her as often because I was scared I would just add to her constipation. I fridged her until she pooped (twice), and then began to feed her around 6 bloodworms every other day. she's been pooping everyday now, but she's at that age where you can see through her stomach and I always see poop ready to come out but has not yet passed. I don't think she's constipated anymore, but I'm not sure and i don't want to over or underfeed her... any advice?

    @Lilith, fridging is not required for fungus treatment. Read my thread on treatment.

    Its probably not pooping because its hardly beign fed, it pooped in the fridge because the lower temp caused it to purge itself. If it stays constipated you can pm me

    Hi guys. Quick question. I have newly morphed eastern newt efts. They lost their gills but they still prefer the water. I have coconut fiber, moss, hidey holes and some food in the temporary habitat for them (waiting for the other newts to morph as well). But they still run back to the water. Is it the wrong substrate? Do they prefer something other than coconut fiber? I've been doing everything else properly (According to my research) but just wondering why they haven't ventured up. Have any ideas?

    My guess is they simply have no reason to leave. Do they still get enough food in the water? Maybe humidity is too low?

    I spray mist the place every day. And I do still feed him. One of them has finally come out. But now I have another problem. They don't look like eastern newts! I am posting pictures on a thread I've started. If you can, take a look for me and see. :)
