Mercury is what is known as "bioaccumulative". This means that it does not in fact leave the body. The more you ingest into your body, the higher the concentrations of mercury will become in your system. This is one reason mercury ingestion (even in small quantities) is a problem.
Fish stays in the body, as in the stomach, for between 30 and 60 minutes. Meat on the other hand, takes 3 or 4 hours to digest.

This link answers a lot of questions about Mercury. It includes sources of exposure and how long it takes to leave the body. For general information: http://www.atsdr.cdc.gov/toxprofiles/phs46.html For specific toxicology: http://www.atsdr.cdc.gov/toxprofiles/tp46.html It appears that most Mercury from fish will leave your body over months, if exposure is stopped. However, some Methylmercury (the kind from fish) can be converted by your body to inorganic mercury. Inorganic mercury in your brain is reported not stay there a long time.

A Piranha is a meat eating fish(like most fish). They grow to about 6 inches long (about 13cm).
no you can eat raw fish like sushi but not if it is left unrefrigerated for to long
it depends what kind of fish they are, and maybe how long you leave the dead fish in the tank. meat-eating fish probably would, but others wouldnt...

As long as the fish is cooked and does not have a high mercury content, then fish is okay to eat while pregnant. Avoid: sushi, shark, macheral, tile fish, etc.
Yea, they do. Almost every fish over 2 feet long will eat other fish in a heart beat

Answer: Not eating meat is better- you are less likely to get cancer, less likely to be fat, it slims you up by not eating the saturated fat that meat contains, and you are also doing good for the environment. Just think, if everyone went vegetarian, think of how many animals would be alive, and wouldn't be chopped up in butcher houses. Not eating meat is great for your health, and in the long run, it prevents diseases. But, eating fish is not considered meat, so DO eat fish- fish is the best thing for you.Answer: No, it is not better for everyone, so it depends on the individual and their body.
