Having been encouraged by the responses of one or two readers of my comments and picture concerning the breeding of Hemidactylium scutatum (Four toed salamander), I would like to offer this series of pictures showing the development of this North American amphibian from egg to metamorphosis. Unfortunately I was not able to include all the pictures in the series I'd selected (14 altogether) but I think you'll get the idea from these.
The larvae are extremely tiny and need to be fed with suitably sized aquatic micro-organisms at first, gradually moving on to small mosquito larvae and such-like. Growth and development are not rapid processes.
Once on land, they will feed on springtails and any other leaf-litter animals as long as they can be swallowed. I kept the environment cool and very wet, always with Sphagnum moss as the main vegetation.

Very nice, it´s always a pleassure to see plethodontids being captive bred. What size were the morphs? And how long, roughly, from hatching to metamorphosis?

Growth and development are not rapid processes.
This is curious to me...Hemidactylium has the shortest larval period of any plethodontid, with estimates in wild populations from 21 to 42 days. I've raised a few clutches and I don't think any have taken more than 2 months to morph. If yours are taking longer you might consider starting some growout tanks. Get some ostracods, copepods, daphnia or similar going gangbusters in a decent sized tank with some oak leaves, branches, java moss, and duckweed and raise your larvae right in this culture tank. Providing them with an abundance of food like this will really shorten the larval period.

I got some F2 larvae this year from 2008 offspring, so apparently sexual maturity can be reached in 2 years.

    Yeah his gills is kinda small and it can be caused by nitrate level, I am taking care of it atm, I am worried about his weight, is he only overfed or are there any kinds of problems there ?

  • MVM1991:
    Well, again, I'm no expert. But I did just read axolotls are supposed to have a body about as wide as their head. The gills I'd say are the biggest problem, which could reduce oxygen intake, which could make a whole mess of problems.

    Hello, I am a new owner of a 3 month old axolotl, and although I have done a lot of research on axolotls, I can barely find any for babies. If anyone can help me with these questions, I would be super happy. How many hours do baby axolotls tend to sleep per day? How many times should I feed it and what would be considered too much (it's current diet is freeze-dried brine shrimp and blood worms, and I currently feed it around 3 bloodworms since they are not that big)? How many times a week should I change the water and how? I have a good filter and use Prime as my conditioner to remove the chlorine and other chemicals, but I still need to figure out how to deal with ammonia and such in the water. How do I clean it's waste (should I use a dropper to easily pick it up)? I need a better cooling system because currently I use ice packs on the side of the tank and I make sure to angle my ac so that it hits the tank.

    I also leave the lid open during the day so that evaporation can cool down my tank. I want to buy a fan, but since winter is coming I won't have to buy one yet. Lastly, what water testers are effective and affordable for a broke student like myself? Please, if anyone has any advice I will love to hear it. I care for this creature too much at this point, but I have no one to help me with caring for it other than the internet :,)

    Hi LauraLobster I am a new owner of axolotls myself and have been getting advice from things like this, I feed mine twice a day on blackworms and brine shrimp blood worms are more of a treat food, a question on where you are keeping you axolotl are you keeping it in the main tank or in a tub also if in the tank did you cycle it first? and if not i suggest tubing it until the tank it cycled, mine are still tubed since I was given bad advice by the shop people about cycling my tank and am still in the process of cycling it. I use pipettes to clean up the mess of my axolotls. I use the API mater test kit for freshwater tanks I am also a student and had to look around to find it the cheapest I could.

    Hi LauraLobster, like you I got my first ever Axolotl back in July. Iv found that he has enjoyed and eaten red wigglers well. They are a good source of protein and help provide the nutrients a young lotl needs to grow up big and strong. You will probably need to break it up into smaller pieces until they get bigger but they are what I have primarily fed my buddy since I got him. He’s actually so picky that he won’t even eat his pellets anymore and will hold out till he gets his favorite wormy.
