Advice on water temperature for community tank?

[Familyfishny]

Hi folks, I have a 37 gal tank (waterfall filter, bubble wall, sand/plant substrate bottom, rock and plants) that has 3 bronze corys, one pleco, and assorted guppies (2 adult, 2 juv, 6 baby). Guppies like warmer water, corys cooler water, but the ranges do overlap. Does anyone have advice on the best temperature to keep all three species healthy and content?

The Corydoras aeneus (assume this is the "bronze") optimum is 25C/75F, but a degree either way is not going to cause issues. The guppies will be fine with this.
