really, I never heard that about a musk. Actually I think what killed him was when my dad dropped in an extra froglet which died on the way back from the watergarden/landscaping store. The crappy ate it, and died the next day. However, he was fine in morning, but when I came back from my summer course, he was dead.
Well I am probaly going to go with smaller fish now in the tank, until i catch a small perch.
