Hello!
You now any type of fish a little bit big,that can do well in a temperature of minimum 19 celsius and can stay with my goldfish?
 
Is this a troll? If it isn’t, can we get some more information?
It's not a troll?
Sorry for the little information, I am looking for some fish that can withstand that range of temperatures to be with my goldfish.
Some catfish, "shark" or some colorful fish

For a 100 gallon

I'd look into some of the loach species, ik quite a few of em seem to be able to tolerate lower temps. Giant danios do well in cooler water. Other then that I can't think of much that tolerates cold water that wouldn't either outgrow the tank or beat up on the goldfish. You could look into getting some US native species but most tend to be allot like cichlids personality wise.

Flagfish are good options that are native, however they are like platys and are small.

Margined Madtom’s are good.

Getting rid of the goldfish would really open up your options, because there aren’t many as of now.
 
Hi A Aqua 4k
Min 19C, but for how long/often? What's the average & max?
Is the 19C here & there storm-occasional, or constant Nov~Feb?

This is an outdoor system? Pond?
If occasional overnight drop, you might be able to get away with a lot via depth/volume, cover and/or a heater.
If a 100gal tank on the balcony, a horse-blanket might help, or make a cover-box out of 1" styrofoam board (what fridges are shipped in) & keep an eye on the weather forecast.

Re. stock: I would absolutely suggest American eel - bright & interactive & bucketloads of personality. Strong, active, ravenous & decor-destructive, too...
