Get some otto, siamese algae eaters. If you want a catfish, try the
bristlenose(acintrus?), bushynose plecos.
I saw some bushynose plecos today, and man are they weird looking. In
fact I saw so many freaky things at That Fish Place in Lancaster that
I didn't stick around for all the tanks. What a baby huh.

Back to the subject of algae eating, I ended up getting two otos last
week, they are pretty cute, and they did such a good job of cleaning
the tank already I am worried about them going hungry now.
They eat cucumber right? Would wedging a raw piece under a rock once
a week be adequate. Leave it overnite and take up what is left of
course.
