Pleco gets a new home

We have a fish that has out grown its tank, a 20 gallon long. For months, he has had to swim backwards to turn his hulking eleven inch body around. Tail bent the poor baby sucked onto the side of the tank; keeping his home clean and his belly full. That is until today. From now on, Pleco will call a new 30 gallon long tank home. Given the extra fin room, I wonder how big he will grow.
Time will tell.
