Okay you guys...jump into bed.

I always thought of clams as living in bed, lolling around waiting for the sea to feed them. So what's this guy doing climbing up one of my return shafts acting like a snail? By the way, I never bought him, he must have hitchhiked into the tank on a piece of rock.

i have one of those, he is about the size of a lima bean and every once in a while he climbs up the back of the tank with his little foot

I'd say this guy's about 1 1/4"
