Get along well with other non-aggressive fish. Do best with other goldfish, but can live with other peaceful fish species. Goldfish put off a lot of ammonia. While goldfish can handle a higher level of ammonia, this level can kill other types of fish and must be taken out of the water.
What is âcalm breathingâ? Calm breathing (sometimes called âdiaphragmatic breathingâ) is a technique that helps. you slow down your breathing when feeling stressed or anxious. Newborn babies. naturally breathe this way, and singers, wind instrument players, and yoga practitioners. use this type of breathing.
Normal Breathing Pattern (Normal Respiration Cycle). Modern physiology textbooks suggest the following parameters of the normal breathing pattern (normal respiration) at rest for healthy subjects: - inhalation is 1.5-2 s. - exhalation is 1.5-2 s. - automatic pause of almost no breathing is 2 s. - tidal volume (the depth of inhalation) is 500-600 ml. - breathing frequency (or Rf-respiratory frequency or respiratory rate) is 10-12 breaths/min. The international physiological norm for the breathing rate at rest is 6 L/min (for a 70-kg man). Normal stress-free breath holding time after usual exhalation (that correlates with body-oxygen content) is 40 s. References for medical textbooks that provide these values are below.
