On rare occasions, salt-water fish have made the transition from salt water to fresh water. Like the case of the Bull Shark that was found 1,750 miles up the Mississippi River.

Depending on the type of fish and the size that you want to put into a tank, I had a shad that was a mere 2 cm when we caught it in a rock pool. This little thing wasn't aggressive and it actually got on very well with my tropical fish, and when I moved from East London South Africa I put it back in the sea. So the answer to your question is NO. I have read all the other answers and believe me I had that "shad" in my tank for a little over 4 years. I believe in using salt in my fish tanks, and that is why it adapted to my aquarium water.

Yes, most saltwater fish cannot adapt to saltwater.

No not if they are "living" in freshwater.

Yes, and they are a little expensive to be killing for the fun of it.
