Hi all,
I just joined the org. It looks like a great place to discuss all things newts!
Here is my situation. I finally found and purchased some marbled newts, a 2.3 group.
I have looked on YouTube (mistake?) for videos/info and have found very little.
I am asking a breeder for help with setting up a breeding environment:
I need to know time of year they breed?
At what temp makes them breed?
What should be the normal temp?
Do they NEED to hibernate first, both sexes?
Can you keep 2.3 in the same aquarium during breeding?
Gravel bottom or bare?
Do they NEED to wrap the eggs around a plant leaf?
Will the others in the aquarium eat the observable eggs?
Do they NEED to get out of the water for any reason during breeding?
How do I take care of the eggs after I remove them from the main tank?
Has anyone used methylene blue in the egg water to prevent infection? (I am a fish guy)
Any help with these questions would be a great help
Thanks in advance, Denis

I have bred them in the past.
They breed in the late winter into spring.
A typical temperature for breeding would be in the low 60s F.
Hibernation is not necessary, but they should have a drop in temp during winter.
Yes, you can keep 2:3 all together.
Bare bottom or fine sand is my preference. Gravel traps dirt and can be ingested.
Yes, they need to wrap the eggs. They can use plastic strips instead of plants:

Some newts eat eggs, most do not. Impossible to predict.
They always need access to a land area. They will rarely come out of the water during breeding season. In my opinion, they NEED to be removed from the water to a fully-terrestrial setup during the summer months.
Raising eggs:

It's rarely necessary to use methylene blue, and may harm them. Newt eggs are very hardy.

An important difference from fish is that newts climb glass.
Lock them in like Alcatraz.
I lost 2 adult marbled newts when I left a lid open overnight.
They were desiccated by morning. Painful.

Thanks Jen,
What temp do you normally keep them at during the NON-BREEDING season? How warm can they handle? Have you ever tried breeding them in warmer temps?
Thanks

On LAND, during non-breeding seasons, they can handle temps into the 70s F, probably upper 70s. In water, I wouldn't push them much above 70F.

If they are in breeding condition, it should be obvious. The males have a crest. No crest, no breeding.

Trying to breed them in warmer temps seems like a contradiction. Getting newts to breed is usually about keeping them cool enough, particularly in winter.

Thanks again,
The reason I ask about the temps is that I just received my group, which were kept in cooler waters and the aquarium they are in is about 74F, all water, and the males are beginning to crest! The females are eating everything in site and their bellis are getting huge! Will they breed in that environment? Has anyone ever tried to breed them this way, in higher temps??
Thanks
