This is very true. Linke & Staeck (1997) report collecting A. lueling in the Rio Tambopata near Puerto Maldonado, Peru. There, they measured the water as low as 15.5ºC/60ºF. I assume that the other species from that region (A. urteagai & A. rubrolineata) can handle these temperatures, too. Of course this is not the low temperatures in which A. borellii are found. In it's southern range A. borellii lives in a subtropical climate where the temperature rarely falls below freezing, but commonly is in the 10ºC/50ºF range during winter days (like right now!).
