As the sinking pellet food neared the bottom and the other crabs came out to pick up a pellet and scurry off with them, the aggressive crab dropped the snail and pinched at both a pleco (Hypostomus plecostomus) and Sir Winston, our spotted pimelodus catfish (Pimelodus pictus), on its way to get its own food pellet.
Later on, the catfish swam low over one of the plecos, brushing it with its barbels, and I joked that it looked like he was giving the pleco a Sneaky Castro. (We watched Deuce Bigalow: European Gigolo recently.) Vogon replied that it would be a Sneaky Winston with that fish.
A little update to my previous aquarium-tagged post: the female red-clawed crabs fight one another just as often as the males did before we introduced the females to the tank. I still get to yell "Bum fight!" at them, but they've learned to ignore me.
