I have had my turtle for 2 years-ish, got it when it was tiny and is now approx 6 inches in length.
I have never had an issue with his health at all, but now I have a worry.
Last week I decided to change the substrate in the tank to washed play sand, based on what I read on these forums. So I did an almost complete water change, added the sand, cleaned the filter, etc etc as usual.
after the change i noticed that the water temp didnt stay up and was down around 70, naturally I assumed that the heater was broken so I replaced it, the turtle may have been seeming to sleep more but I attributed this to the low temperature, and my own paranoia (checking constantly after the big substrate change!) - I also suspected that his eyes looked a little puffy, but when taking him out for inspection it wasnt so obvious.
Well today his water temp is back up above 75 but I notice that his eyes are swollen, and obviously so. Should I attribute this to the water change and if so what should I do? Should I just call a vet this afternoon (I confess I have never taken the turtle to a vet, and am now looking for one in my area) ?
