i have a loggerhead musk turtle that has been living in a 10 gallon tank with a pile of rocks for some time. I have a 40 gallon breeder i would like to put him in with a planted yard in it. I also have a chubsucker who is living in tight conditions in a 29 . i would like to put him in the breeder along with some minnows, so does anyone know about musk turtles? are they night predators, will they attack large fish ? i figure the chubsucker is too big, and the minnows too fast, unless they're sleeping.
