Slug and other gastropods have what's called an open respiratory system. Humans, for comparison, have a closed respiratory system. Essentially, slugs "breathe" through the pours of their skin. Oxygen enters and carbon dioxide exits.
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
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.
Anaerobic bacteria can survive and reproduce without oxygen by obtaining energy from other sources such as fermentation. Some organisms like certain deep-sea creatures and certain bacteria can adapt to living in oxygen-deprived environments by using alternative metabolic processes. However, the majority of complex organisms, including animals and plants, require oxygen for survival.
Most people can live comfortably without needing supplemental oxygen at elevations below 8,000 feet (2,400 meters).
Prokaryotic cells can be aerobic (requiring oxygen) or anaerobic (not requiring oxygen), while eukaryotic cells typically require oxygen for aerobic respiration. However, some eukaryotic cells can also perform anaerobic respiration in the absence of oxygen.
No. No animal can live without oxygen
No a snail can't live in a snail.
Yes
yes

Snail do not need company so the death of the fish will not affect it in any way other than to leave more oxygen available for the snail. It will be perfectly OK for several weeks provided the water does not go bad.
Yes, there are types of snail that can live underwater.
You cannot live without oxygen for more than 5 minutes. :D

you cant live without oxygen
most snails do require oxygen as they have also got lungs like everyother human being, however, some snail like the molusk dont require oxygen and live in the water
Many types of bacteria can live in Anaerobic conditions, I.e they don't need oxygen to live, as they create energy using anaerobic respiration.
