Hillstream loaches, wcmm's(white cloud mountain minnows), pearl and zebra and leopard danios, weather loaches, albino/bronze corys, common plecs and bloodfin tetras are all examples of fish that preferred to be kept in sub tropical temps- sub tropical temps are usually in the range of 19-23 degrees.
Are you sure you mean bronze cories and not peppered cories? I thought it was the peppereds that preferred the cooler temps, and that bronzes can cope with tropical temps quite happily.
