One of my male platy has both yesterday and today put himself in the small crevice between the heater (which is horizintally at the bottom close to the gravel) and the glass. He's resting on the gravel, with his body against the glass and the heater. He moves every few seconds, but he's usually up around the top with the others.
Could he be sick? I've not seen this behavior before.
