Best Algea Eater?

Hiya

I am having a problem with my main 55 gallon community tank, and the
problem that as summer is coming I am getting a lot more algea in my
tanks and on my plants. My catfish cant seem to keep up, so what are
the best alea eating fish I can buy? Some people reccomend a
plecostumus but they sklulk around in they corners and hide a lot, so
I don't really want one of those. So what is my next best option in
buying a good algea eater?

Thanks

Paul
