can pleco live in saltwater??

Answer 1

As in a marine tank? No.

They can tolerate a small anount of salt in their water (about 1 tablespoon per 5 gallons), but they're generally sensitive to high amounts of salt.

If you have a saltwater tank and are having problems with algae, see this link to identify they type(s) of algae you have and saltwater fish and inverts that may eat it: http://saltcorner.com/sections/guest/algaepage/algaepage.htm

Answer 2

No, Plecos are freshwater fish. If you put it in saltwater, it will die within a couple of hours as the salt slowly burns its gills and dehydrates it by preventing osmotic "drinking".
