Are there any cases of parthenogenesis in N. crocatus? I found a single egg (don't know if there's more), but I only have one female in the tank for the last 2 months. I have absolutely no idea how this egg came to be.

In many cases females will lay if they are gravid regardless of whether or not the eggs were fertilized. This goes with most caudate species. If it ends up being fertile it was the result of breeding before it came to you.

Thanks, that clears a lot of things up! I always thought the unfertilized eggs were just reabsorbed

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
