Recently about 2 days ago i purchase a adult musk turtle about that is around 5 inch. He is in a 30 gallon tank right now with a basking area and zoomed 2.0 uvb light, the water temp is about 75-80F. The turtle doesn't seem to move much and just stays in a corner with its head out. It seems very shy and put its head back when i get near it. Once in a while it would go the middle level of the tank and then sometime it was just float around the top of the tank. It show no sign of coughing or sneezing. Is this concern or possible problem with the turtle.
Thank You
