They are cold-blooded and have a lower need for oxygen.
The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.
Yes the altitude of the area does affect the breathing rate becaue the higher you go the lower the air pressure and the the lower you go the lower the air pressure.
jazz
Decreased breathing rate > more Co2 and less O2 in blood > more acidity > Lower PH level
Having several layers of gills on the fish helps to increase the breathing rate of the fish.
It will raise there respiration rate. I did an experiment on this about 5 years ago.
i dont know but its a cool question dude because it good

The breathing rate and pulse rate are related proportionally. If the breathing rate increases, so does the pulse rate. The pulse rate is an indication of the breathing rate.
Emphysema causes a higher breathing rate. A person with emphysema can be "air hungry" even when getting external oxygen by mask or cannula.
They don't have a lower rate of anything. There is a higher rate of premature birth, children with birth defects, and problems in development. As children they have more breathing problems and allergies living around smokers. That doesn't fade away as they age because of the breathing in of second hand smoke affects them all of their lives.
