We picked up the little guy yesterday from petco, we checked the salinity levels and temp requirements and everything is right on where he needs it. When we put him in he just chilled on the crushed coral and as soon as the light was off he was off to the races. He scaled the side of the tank and is now hanging up in the top corner of the tank with an arm sticking out of the water. I'm assuming this is a natural behaviour. Does anyone have any pointers for his care?
