The press has recently been abuzz with news of a newly discovered species of catfish that eats wood, of all things. But since at least the 1990s, scientists have known that some catfish species consume wood. The news stories I have read havent done a particularly good job of describing why journalists are so intrigued by this discovery, beyond the obvious twist: a fish that eats wood.

But these fish are popular pets: If you look at the tropical fishes available for sale in your local pet shop, then you have probably seen at least one of the dozen or so species that are placed into the genus, Panaque. (For example, today in my local pet shop, there were three Panaque species - all coyly hiding under submerged bits of wood, so I couldnt get a decent photograph to share with you.)
