The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.

rest.
Normal rate is 30-50 ave is 40
Having several layers of gills on the fish helps to increase the breathing rate of the fish.
inspiratory center of DRG
It will raise there respiration rate. I did an experiment on this about 5 years ago.
The normal breathing rate for a 2 year old boy is around 30 breaths per minute. This can vary from child to child, however.
The normal rate and depth of breathing is established in centers located in the brainstem, specifically in the medulla oblongata and pons. These areas control the respiratory rhythm and coordinate the muscles involved in breathing.
independent
They are cold-blooded and have a lower need for oxygen.
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.
