Newts!

[Gnag the nameless]

It honestly depends on what kind of newt you are talking about. Please, find out what kind they are. Then we'll be able to get down to facts, not guesses.

To be honest, I don't suggest ever mixing species. It's just not a good idea.

Newts require pretty big aquariums from what I have heard. I would say
20 Gallon- minimum, 55 gallon- optimum

Like I said, we need to know the kind of newt.

Like Caspian said, need to know species.

General rule of thumb with Newts though is they are too shy to be kept with fish. When kept with fish they usually become stressed. They also require cooler water than most tropical fish can tolerate.

Mixing amphibians is a big fat no. There is a huge risk of cross contamination of disease, toxins, parasites. You name it, it's just a cardinal rule of keeping amphibians in general. You want to go with a species only tank with these guys, for the most part (and amphibians in general).

Agreed, mixing species is a bad idea. I've heard of people mixing Firebelly toads and Firebelly newts, and having one or the other dead the next day due to the toxins both species secrete.

I second Michael on that, newt's are generally very shy and best kept alone. I've seen more than one enclosure online where a newt was kept with fish, and all it would do is hide.

I've done some research; apparently, if you are obtaining a newt in the larval stage, you can feed it bloodworms, tubiflex, brine shrimp, and water crustaceans, the latter I've never heard of to be kept as feeders.

If you're getting an adult, I know from my friend's experience with newts that crickets and earthworms do fine for newts.
