Why is your turtle swollen?

If your turtle is swollen and you notice that his shell is softening it is blood poisoning.

If treated by a reptile vet immediately your turtle will be put on a drip. However if left a few days there is no cure and the best thing to do is put your turtle out of misery as it is a terrible death.

I am not sure as to why this happens, it has only happened to one of mine and i did everything right.

unfortunately i could not find a reptile vet in time(they are hard to find)

Never keep other turtles in the same water with sick ones.
