Axolotl and turtles in same tank?

ok i have an axolotl in a tank with fish already but that tank gets to hot for my axolotl so i was wondering if it is ok to put the axolotl in the tank with turtles in it. it is much cooler and bigger. i was told that turtles do Attack fish but only if it is smaller than the Turtle. my axolotl is bigger doesn't and Attack anything so i don't see why the turtles would Attack it
