my ghost knifes were the same. i have a brackish tank, so i can have certain salt water fish. i had a starfish and the ghost knifes killed it within a couple of days.
also, i had a clown loach at one time and the sharks killed it... for a fish to last in my tank, he's pretty much gotta be a badass. lol.
