Sucker

This is a Plecostomus.

Or as he's known in our house, Paul the Plec.

He is a wee catfish and is about 3 inches long. They can grow to about 1-2 feet which is a tad big for my tank and live for about 10-30 years.

If he manages to get to that age hopefully I'll have a bigger tank for him to live out his old age in.

He just spends his days hanging upside down on the side of the tank and is the laziest fish I've ever came across.
