My musk turtle has been acting strangely for a couple of weeks, he/she (I’ll come to that in a minute) is spending a lot of time out of the water either under the UVB lamp or on the other dock at the other end of the tank. Also there is a lot of scrabbling at the glass trying to escape when active.
Here’s a picture of a common position:

Coming back to the question of he/she, I’ve found so much advice online I have no real clue on how best to tell. It only came up as when I discussed the behaviour with a local vet they suggested if it is indeed a female she could be gravid.
The water temp is 25deg C and I had it tested at a local reptile shop and it was ok, the nitrates were slightly high but it had been a week since a water change. He/she is eating some food but not as much as usual...
Any ideas please?
