I'm currently raising about ten Alpine newt (apuanus) larvae and everything's going well, but my goodness can they eat! They get two net fulls of live daphnia/mosqueto larvae mix, along with frozen bloodworm and the occasional tiny chopped worm daily and their bellies are visibly bulging and yet they still frequently rip each others legs or tails off and eat them! I've raised C.pyrrho larvae for the past two years and they seemed like gentle creatures, I certainly never saw this level of gluttony and cannibalism!
So basically what I want to know is:

Is it possible to overfeed them? Not from a fouling the water point of view as they swallow everything!

Can they digest everything they eat in a day, or do they just carry on swallowing stuff and pass what they don't digest as waste?

Is it normal for them to be so cannibalistic, even when they are obviously well fed?

I'm going to say the more they eat the better, but let's see if anyone else has experienced larvae overeating.

I agree with Otterwoman, except perhaps with ostracodes. I had some problems when feeding larvae with ostracodes but it was not with alpine newts.

Moreover, if food isn't sufficient, dominance problems can occur, especially with alpine newts (a personal observation).

When raising apuanus i never had a problem with over-feeding, but i did have a problem with nutrition the first time. Make sure they get calcium rich foods. I would skip the bloodworms entirely and focus on earthworms and crustaceans.
They are vicious little things, but they make up for it by being gorgeous.

Cheers for the replies, I guess if you're born into a temporary puddle or road rut, the pressure's on to morph as quickly as possible!

Azhael, how would I spot malnutrition in larvae, deformity?

The problem is that by the time you can tell something's going on, it's already too late. In my case the first two i ever raised grew very fast and very well at first, but when they approached metamorphosis their growth became stunted, their development stopped (they looked neotenic-like) and from then on they lost weight and deteriorated.
I have to say that i've had problems like this because the water in my area is ridiculously soft to the point that they have to artificially put some CaCO3 in it so that there is any at all (and it's still one of the very softest in the country). In different conditions of hardness you probably don't have to worry as much as i've had to, but nevertheless there is no better prevention than offering only calcium rich foods. Also, as far as i understand, apuanus come from calcium rich territories in Italy, so it's best to be extra paranoid. I never had any such problems with pyrrhogaster or orientalis, but i've had them with european species, so their tolerances are clearly very different.

I understand, thanks for the heads up. I raised my Leopard tortoises from hatchlings, so I should know how important calcium is to fast growing herps.

    Do all impacted axolotls float? I'm worried about my two juvenile axolotls as they both have bloated stomachs and I have some plant substrate in my tank. The substrate is very small and breaks apart easity but could this still cause impaction? They are not floating at all and still eat a lot. I've been feeding them bloodworms.

    I have a question, I’m looking into getting one or two Axolotls and I don’t know if I should just get one or get two. Planning to get them as eggs.

  • CrazyForLotls:
    @SunnyAxies, It honestly depends on how much space you have. Two axolotls in the same aquarium would need a minimum of 30 gallons. (at an adult size) If you end up with opposite genders, you would need two 20 gal tanks. Males and females can't be kept together since they will breed and overbreeding the female is harmful to her body. Another factor would be if you think both eggs would survive. Sometimes axolotls hatch with defects and either die or should be euthanized to prevent them from living an uncomfortable and/or stunted life. It's sad, but it's for the good of the animal.

    I made a huge error, I’m about to cry because I don’t know why I was so stupid. I decided to clean the sponge and other stuff in my filter while I left the filter running. (I took out the parts in the filter to swish around in dirty tank water). Bc I left the filter running, all the gross stuff at the bottom of the filter filled into my axolotl tank. My tank is like brown now. I was trying to unclog something in my filter cuz it wasn’t running right and idk why I left it on I literally don’t know. I tried to take a bunch of water out snd replace it with fresh water but it’s STILL brown.

    Hello! New caretaker of a paddletail who is supposedly 24, and seems to have been poorly cared for. Supposedly was fed earthworms or redworms, but every time I've pet-sat for her, she just chomped at the worm once or twice and left it, to be removed a day or two later. Now I have a bigger, clean tank and have been trying mainly frozen bloodworms and brine shrimp, thawed with spring water and fed with a dropper. She ignores bloodworms, goes for the brine shrimp eagerly, but seems to spit a lot out, and ignore most. I'm not sure I can make myself chop up worms (😳) but I want to help her. She also regurgitated an inch-long, seemingly stiff, straight, dried up bloodworm! I don't even know where that came from!!! All help appreciated. Thank you.

    Hello anyone that can help! I’m a breeder and was wondering how to make pellets as well as salmon pellets! I’ve seen some recipes around but they contain crickets which I thought were no good for axolotls because of the chitin. The amount taht I have devours 2 pounds of pellets in a week 😂 so any help would be great. There was another lin las well for two other pellets but I’m not sure if it lets me open it because I am in the Us?
