Fish

Cory catfish are so cool.  They remind me of cows.  The way they graze along the bottom of the tank, the vacant stare, the way they lay around in herds -- there's an expanse at one end of the tank where they tend to hang out together, we call it the cory pasture.  The albinos are the most active.  Unlike the other cories, they seldom sit still, and often to skittering along the glass at top speed, occasionally colliding with each other.
