hi i've had my axolotl for just over 3 months now and hav noticed today that hes ( i think its a he) not his usual self. hes less active and were he normally runs and hides wen im cleanin his tank he leets me get up close and doesnt flinch. i have just done a water change incase it was this and he seems to have perked up a bit. water conditions should of been ok because i clean him out every couple of days. could it be that i need to get a heater??? as the temperature has dropped over the last couple of days and this is all i could think of please help any advice would be very much appreciated. jodie
