I'm not sure about the plants but most tropical fish should not suffer
too much if the temp goes over 30 C temporarily. I would suggest that
you protect the tanks from direct sunlight and reduce the lighting
hours (heat from the light bulbs). More areation could help too. If you
have a room in your house that is colder than the rest of the house,
you could also try to place the air pump to this room. The colder air
should thus reduce the water temp. If the temp is really bad, you
might consider changing small amounts of water several times per
day to add colder water to the tank.
