20gal cool tropical fish

Any suggestions for a 20L that would stay at the mid 70's temp range? I want to set up a tank that has fish that are able to stand cooler temps. It would also be planted.

white cloud minnows should do well.

I have found that most tetras and barbs do quite well in the mid 70's. Most of my tanks are kept around 75 degrees and the fish seem to be happy and healthy. Good luck.

You could fill it with apistogrammas. I keep mines in a low planted 20 long tank and the temp is usually around 70 degrees in the morning and 72 degrees at night and they have already spawned for me twice in 1 month. And sometimes it even goes as low as 65 degrees because of my home AC.
