Hi there, I bought the smallest worms I coukd get besides blackworms etc. and the worms I got have a yellow fluid in them. I read online it's actually used for cleaning bacteria, but if my newts are eating these will there be any negative side effects?

Its called coelemic fluid and in Red Worms (Eisenia fetida and Eisenia hortensis) is excreted as a defense mechanism. Since it is so strong smelling many newts will not immediately accept them. I've heard of toxicity issues stemming from their use over time but have never seen any data to back these claims up. I feed them to my newts along with night crawlers and earthworms. The only newts that don't eat them are my Neurergus crocatus and a few picky Alpines.

    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?
