hey, I was just reading along and came across "tiger shrimp". I am looking for shrimp to put in my 15 gallon fresh water tank that contains guppies and sword tails. I looked on google to see what these tiger shrimp were. all i got was that they might be salt water and the kind you eat at restranuts. If any of you could help me out with figuring out if this shrimp is right for my tank, that would be great.
