Keep the tank lights off (if you have live plants, you might be able to reduce the light period, plants can maange with 5-6 hours daily, and this could be during the cooler morning so lights could be off in the mid to late afternoon); keeping the tank open (cover) unless you have fish that might jump--and many will; feeding less (food digestion increases fish's need for oxygen and increased physiology); ensuring good water movement (air stones, filter flow) and at the surface (to increase oxygen as well as maintaining lower heat). Some suggest a fan blowing across the tank surface.
Years ago I livedin a condo and during heat waves lasting a couple weeks it would be around 90F during the days, so of course the tanks were in the high 80's. I never lost any fish. I now am in a house with the fish tanks all in one room, and I have a portable air conditioner than will keep the room at 80F during warm days.
