Just bought 2 pastel red eared sliders that arrived today. One of the little guys constantly is swimming in circles. He submerges well and looks healthy but he just does this. We have just about written him off as "special" and intend to do what we can to give him a great life but I decided to throw the question out to you folks. Any ideas? We have considered raising the temp of the tank to hopefully help any possible respitory problems (but he is capable of submerging). Any other ideas?
Thanks for your time.
