My girlfriend would like a way to control algae in her tank. She has SAEs that took care of her brush algae, but they don't seem to do anything for othger forms of algae (hair-like) on the plants. She is looking for an alternative to plecos and otos, because she doesn't like them. Any suggestions? Are Hillstream loaches any good for cleaning up the algae? Any other fish? Thanks Jeff Malmquist
