I have noticed tonight my turtle has pink spots on her plastron and I have read that it's a sign of Septicemia. The turtle has no other symptoms of blood poisoning except pink spots on her plastron. She eats very well, basks and is very active, she is growing very fast and I was hoping it was just growth because she's around 4 months old at this point and is already 2Inchs. I've had her in a 10-gallon tank for the last 2 months because her big tank cracked and It can't hold water anymore, someone I know said they will give me theirs and I've been waiting for that. I clean out her tank once a week and do water changes in between and maybe she's reacting to a bad environment? she doesn't have swelled eyes, no difficulty breathing no loss control of muscles or weakness just a discoloured shell. I can't afford a vet bill right now unless I really need to go. Has anyone's turtle looked like this before? its this normal for a fast-growing turtle to look like? also, the picture I attached makes it seem redder since it was taken at night.
Thank you!
