I had two RES since Septemeber, but the bigger one died today. I'm going to clean the tank really well. Im wondering if I should get a new turtle to go in the tank. I don't want the other one to become depressed and die as well. I think the other died from a respiratory infection (I googled his symptoms), he had been sick since Friday, so he didn't last long enough for me to take him to the vet. Should I be worried about the one that is left??
