Hey there I have an outdoor 20gallon tank with 8 white cloud minnows 

and I was wondering if I could find some nz killifish and add them in there?

it is very hard to find a cold water fish that won’t eat white cloud minnows.

the temp drops to possibly 5 degrees c. 
and Will they eat my minnows? 
thankyou!

killifish would not be happy in a cold water thank. White cloud minnows are named after the white cloud mountains in China where it can get pretty cold,. Killis come from water a lot warmer than that,. You are likely to have problems with velvet --particularly with Nothobrancius

 

Sorry like the nz ones that are in nz stream etc

NZ has no native killifish, there are the invasive Gambusia in some waterways that loo like guppies

Ok thanks but can they go in there?

gambusia are nasty by nature and would probably give the white clouds a hard time. They cannot be legally bred either, and since they are live bearers---not easy to not breed.

really? is it legal to capture them? 

No it isn't. You can't catch, distribute, or release, gambusia in NZ. Gambusia are vicious and attack native fish.

Yes but i what to take them out and put them in my tank, Florida for example encourages this under invasive removal 

You are allowed to catch them at all. Probably because of idiots who do so, discover how nasty they are, then release them in the nearest waterway that probably didn't have gambusia before they released theirs into it. I would imagine gambusia are a lot more widespread in Florida. Rules vary here from council to council. They are more of a problem (the gambusia, not the council) the further north you go with warmer temps.

Do you mean not allowed?

Yeah it seems you are very distant from nature in NZ.

If i read the law right i can take non native fish of i want to eat them?

What about the guppies they are much More friendly?

In other countries I've just gone to the water found something invasive colorful fish, loved it then sold it when I left the country 

If i say I'm fating then up for sale is that legal?

 

My typo, of course I meant  you are NOT allowed to catch them at all.

What do you mean by being very distant from nature?

Fishing laws vary in different parts of the country so it would pay to check the local laws with your council, or Fish & Game.

We have a lot of unique native flora and fauna here, due to our geographical isolation, so differ from many other countries when it comes to catch and release.

it seems all hidden behind laws that you have no navigate to even touch it.

else where if i wanted to teach some one whats in the water i'd just go out there with a net and see for my self, sending most back but maybe keeping one for my tank and thats normal in all of the world we are part of nature and know how to respect her. but in nz it seems you have to be certified to even shit in the woods....

 

Most of the time we can catch and release/keep etc too but not if it involves native, or invasive, species.

We don't mind you shitting in the woods, as long as you are off the path, so nobody stands in it, it is the ones who do it in the waterways who are more of a problem! ? 

What is the that's not native or invasive.? How do I know when there in the water. 

Yeah point proven, always cover your shit, one of the first rule of bushcraft
