Hi PowderTang, the starfish have been with me for a week and 2 days. Still doing as well as before though there was once or twice I thought the body felt very soft and limp rather than the usual hard and solid.
Kinda think it's the temperature causing this to happen. During the time he was limp and soft, the temperature was around 30. The cooling weather these days have helped to bring the temperature down to 25-26.
