No, only aerobic bacteria require oxidase.
Aerobic bacteria uses oxygen for cellular respiration and anaerobic bacteria doesn't require oxygen to survive. ˇ_ˇ 
Yes, it is possible for an anaerobic bacterium to test positive for cytochrome c oxidase, although it is uncommon. Some anaerobic bacteria may possess cytochrome c oxidase as part of their metabolic pathways, particularly if they can utilize oxygen in specific conditions or if they are facultative anaerobes. However, most strict anaerobes typically do not have this enzyme since they do not utilize oxygen for respiration.
The term that best defines a bacteria that can survive without oxygen is "anaerobic." Anaerobic bacteria do not require oxygen for growth and metabolism.
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
Bacteria do not breathe in the sense that we do, but many do require oxygen. These are called aerobic bacteria. Some bacteria will use oxygen if it is present, but can function without it. These are called facultative anaerobes. Still other bacteria will die if exposed to oxygen. These are called obligate anaerobes.
Bacteria that do not require aerobic respiration are known as anaerobic bacteria. These bacteria can survive and grow in the absence of oxygen by using alternative electron acceptors in anaerobic pathways such as fermentation or anaerobic respiration. Examples of anaerobic bacteria include Clostridium and Methanogens.

Anaerobic bacteria do not require oxygen to thrive and grow.

Anaerobic bacteria do not require oxygen to grow. Examples of anaerobic bacteria include Clostridium and Bacteroides species. These bacteria can survive and grow in environments with little to no oxygen.
Anaerobic bacteria do not require oxygen to live. They are able to generate energy from sources other than oxygen, such as fermentation or anaerobic respiration. Some examples of anaerobic bacteria include Clostridium and Bacteroides.

The oxidase test is used to differentiate bacteria based on their ability to produce cytochrome c oxidase enzyme. It helps to differentiate between oxidase-positive bacteria, such as Pseudomonas and Neisseria, and oxidase-negative bacteria, such as E. coli and Enterococcus.

Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.
No, bacteria do not always require oxygen to grow. Some bacteria are able to grow and thrive in environments without oxygen, a process known as anaerobic growth.
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
