The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.
It doesn't. Species, water temperature and excitement/fear or activity will change a fishes breathing rate. The fishes size has no effect on it at all.
yes . . depending on availability of oxygen, breathing rate changes
it is sort of different for all fishes .for example a sperm whale breaths 3-4 times per minute
yes, it will
jazz
yes
Yes it does.
No i is not. In fact a scientific survey revealed that lionfish were eating tropical fish. When lionfish entered an area al the tropical fish had there survival rate slashed by 80% as they fell prey to these lionfish.
Having several layers of gills on the fish helps to increase the breathing rate of the fish.
Carbon dioxide
It will raise there respiration rate. I did an experiment on this about 5 years ago.
5bpm
No. What you may be thinking of is aerobic respiration (normal breathing), for which the breathing rate (as well as heart rate) is typically a bit slower in men.
