Paradise Fish

yea should be fine might have a little conflict here and there nothing bad

have some plants for hiding if needed
 
they do just as good in tropical conditions

i would just be worried about their aggression
 
I had a male Paradise and a male Bolivian Ram in a 20g tropical set-up and they got along pretty well. The paradise spent most of the time at the top and bolivian at the bottom, sometimes when they encountered eachother there would be a bit of flaring of fins, bit of aggression but nothing major. They pretty much just avoided eachother. Basically aggression is a possibility, but if you want both types of fish then give it a go.

Paradise fish are from Asia so they are a tropical fish, they are however a very hardy species and can handle lower water temperatures (suited to temperate tanks aswell).

:iagree:

On the other hand, not all fish that live in Asia are tropical species. If you take a look at hillstream loaches, they are coldwater to subtropical species relishing the cold environment best (though no lower than 68 degrees Fahrenheit but no higher than 76 degrees).
 
Stocking depends. Paradise fish can be nasty at times but from what I have heard they seem kinda like bettas where the individual personality is key with stocking. Personally, I would have a back-up tank and give it a try.
