Water change?

Is your tank near a doorway? Drafts make one corner of a tank cooler than another. Stick a thermometer to a suction opposite the corner a heater is located

Otherwise, most tetras are known to school away from cool currents when not feeding. They prefer to just mellow out in +80F soft water
