Well, the pleco i'm going to go with actually looks a little similar to a zebra, for a lot less money, and it's definitely an algae eater... check it out:

You are taking about the L018. You are right they grow huuge. The L081 grows to 18com/7in also on the big side but not that big. If i'm not mistaken i think theres a 3rd gold nugget....

I'd second the comment on the clown. They don't get big and they don't bother other fish that I have ever seen. They do seem territorial in that they will defend their hiding spot from other fish, but I have three that have enough space in a 55 gallon to avoid conflict. At least one of then even eats black beard algae.

The only downside is that they are reclusive and nocturnal and I seldom see them.

And they're not excessively expensive around here.

I'd have to go with the Zebra, since their natural habitat (along with many, many other species) is slated to be wiped out.
