Sometimes a sick frog will spend MORE time near the top too, but it depends.
One last thing: clawed frogs should be kept 76 degrees or below. Too warm of water can make xenopus more susceptible to bacterial infection.
Xenopus were my first frogs I ever kept but from experience, they are more susceptible to bacterial infections because they are touchy about water temperature and quality.
