I am becoming obsessed with my pleco

Horrified, yet at the same time - tittilated - is the phrase made famous by the Codco ladies. And it's appropriate here too. My pleco, which I got to clean the algae in my fish tank - is fascinating me. He/she is like a creature from outer space, and I can't take my eyes off it. It sucks things, and has wings on it's sides, and fake eyes. Why would he need fake eyes? I have NO idea...
