Hi guys. I know this has been asked in other threads but I won't be able to put my mind at ease unless I ask these specific questions. I've just moved my Murray River turtle into an outdoor pond (in Melbourne) Everything is going well but the temp in the morning is around 15 degrees. Probably lower throughout the night. We are still having hot days in the high 20's every now and then. With the weather changing so often, should I heat the pond to keep it a stable temp (around 20 degrees?) or will the turtle be OK. Also, with the water temp being around 15-18deg Should I be feeding as normal? And when should I stop? Or is all of this normal for this time of year and should I just leave the heater off and feed normally until the water temp drops to around 12-13 degrees in winter? I don't mind paying to heat the pond if I have to but I want to make sure I'm doing everything right. Thanks in advance.
