One of our two-year-old sliders passed away after vomiting too much blood. We took him to the vet, two of them separately, but none of them could explain why the vomiting of blood came from and he still passed away. They found tumours in the oesophagus when they did the endoscopy. The vet said he didn't know if the tumours or other things drained his blood. The slider had some pyramiding and I think he was overfed, but none of the vets talk about the pyramiding and overfeeding even after examining them.
I know I should listen to the vet, but since he cannot explain anything I am wondering if any of you here may have an idea why he died. I am trying to understand if it was because of our setup, so we could change it asap.
The remaining two-year-old is very active, but I also think she's overfed. We are reducing what she eats now. Recently, we find some seaweed like thing in the tank even none of us gave her seaweed. It is not algae plants. Any idea if it is something of concern? She is eating, basking, and doing everything normally.
Our ten-year-old slider is fine and not overfed, although he seems to move slower than when he was young. He still slides down very quickly from the rock though. I suppose it is a normal thing he becomes slower because his shell is heavier?
