I'm trying to get ideas for the right population It's a 2500 liter unheated aquarium/ upper pond positioned in my garden. Temp varies depend on the month ... min 8 Celsius degrees max 35 Celsius degrees. Filtration 15,000 liter per hour

You can never go wrong with koi. If you want something more predator like, you can try some local gamefish, like perch, largemouth bass, or bluegill.
