I have a RES about 4 inches and it's really sick. For about 3 weeks now it's not eating just basking all day. It lives in a 60 liter tank with water heater and filter. The water is treated with Aquasafe. When it's out of the tank it has moments when it raises the head straight up and starts running and jumping almost doing backflips. And then stops for a while but repeats the same running with the head up. And also does not open the eyes but they not appear puffy. Does not gasp for air and there is no discharge or mucus. It floats straight in the water. Really don't know what to do. I gave it baths with some vitamines that the vet recommended and some ointment for the eyes. I have one other RES but it has no problems and they share the same living conditions. Please help
