It will raise there respiration rate. I did an experiment on this about 5 years ago.
The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.
The temperature of the water can affect the amount of available oxygen for the fish. In a warmer temperature, the oxygen tends to be lower (and even more so if there is algae), thus their breathing rate tends to be higher. In cooler water, there is more oxygen than warmer, and for the most part, their breathing rate tends to be more shallow.
As the temperature changed, the fish's breathing rate increased or decreased accordingly.
As the water temperature decreases the fish's breathing rate decreases as well. If you increase the temperature the fish's breathing rate will increase back to it's normal breathing rate.
The warmer the water the faster the metabolism. Beyond a certain point the fish can no longer breathe because the higher metabolic rate demands for Oxygen exceeds the fishes capacity/ability to gain sufficient Oxygen from the depleted warmer water and the fish dies from asphyxiation. As the water gets cooler the opposite occurs and the fishes metabolism slows down. As the temperature approaches freezing the fish comes to a standstill. The fish no longer moves and its breathing is reduced to an absolute minimum. Any colder and the fish will not have the energy (heat) to enable it to breath and it will die.

It will slow down Because the fish will able to relax and calm down in cooler water. It will be able to slow down the process of breathing. there is more air to breathe in cooler water so the fish will take longer breathes. me and my frineds did an activity about that and the answer is that it actually increases by a little
Goldfish breathe slower in cold water because there is more oxygen in cold water. Therefore they don't have to breathe as much to get the amount of oxygen they need
Having several layers of gills on the fish helps to increase the breathing rate of the fish.

its the respiration rate of the goldfish.
