Behavior Modification w/ Powerheads

[waverider]

I have three clownfish. Larry, Curly and Moe. Little Moe was the little runt that made it into the bag at the fish store. I had selected a larger clown but I figured the little guy would be the spice of life. His big brother's occasionally pick on him, as just happened now. Tonight his big brothers were unusually bullish. So, I have a set of 3 powerheads. -Two moderate 1500GPH variable power that run normally, and a big 3500GPH that I normally keep off, but use occasionally to blow out my system.

A blast of current and all squabbles over.

Half an hour or so and I'll let them all relax.
