I agree with post a few up. I keep many species of frogs and toads, and used to keep newts. It is best to never mix fish, newts and/or frogs. Frogs and toads, even newts and salamanders, all carry different types of toxins in their skin. Not toxic to you and I, in most cases, but with other species. This is their defense mechanism in the wild.
Fish can also carry parasitic nematodes that can cross over into frogs and newts, infecting them and eventually killing them.
I hope my reply helps. :)

Many of the species of amphibian with toxins in the skin are not toxic in captivity. Most of those toxins come from the natural diet that these animals eat in their natural habitat.
I do agree that mixing them is not smart, as most are cannibalistic, too.

This is not to say that frogs don't carry stronger toxins when in the wild...especially frogs like dendrobatids. However, this is not to say that simply because a frog now lives in your vivarium, it becomes a "non-toxic frog", especially when mixed with other species. One of these days, I'll learn to stay out of these forums...geez

The dart frogs are a good example of what I was referring to. In the wild, they are toxic... due to their diet. In captivity, they are non toxic... due to change in diet. The toxin in the wild dart frogs comes from ants that they feed on, if I remember correctly. I'll have to look it up, but I do remember that the species of insect they feed on in the wild is where the toxin comes from.

Although this thread is somewhat older, I thought I'd post to reaffirm the previous poster in some important knowledge.

It is absolutely true that some animals get their toxins from their diet in the wild and, therefore, lose their toxicity in captivity. Poison dart frogs are the perfect example of this because, as the previous poster mentioned, they eats toxic ants and then metabolize and concentrate that poison thru their skin pores.

That said, it is dangerous to assume that an animal that is toxic in the wild is not toxic in capitivity without taking certain precautions. First, get to know the animal in question. (Hello, my name is..... errr.... I mean educate yourself abou the animal!) Second, determine if your source for your pets is using wild or captive bred stock. Third, ask what the animal has been fed and about its environmental housing conditions.

This should, under most conditions, allow you to determine if it is possible to purchase a captive-bred version of an otherwise toxic wild animal. If so, and if that animal has been fed and housed in conditions that would keep it from producing its toxins (assuming that it is the sort of animal that requires certain conditions for toxin production), then you are likely in much better shape. However, whenever mixing species, YMMV....

All the best....
