I don't know of any semi-aggressive or aggressive cleaner fishes. I would normally recommend cory cats, but they are peaceful fish. I think you are in the same boat as those with cichlids...without cleaner fishes.

I don't know if you are using a light (or if you have plants and need lots of lighting), but if you reduce your lighting you provide during the day to under 4 hours, you should reduce the amount of algae produced. Also, most of the time biweekly water changes help. Sometimes though, no matter what you do, algae will grow like crazy. Snails sometimes help, although I cannot recommend a specific species that loves algae more than another and that will not reproduce like crazy.

Hope this helps.
