Hard, but not impossible. The tough part is meeting their feeding schedule, since the polyps are nocturnal. It will take some dedication to figuring out a feeding regimen for it. If you're having trouble with nuisance algae it's a no-go for that reason alone. They tend to become algae magnets in such systems, and the polyps evenetually get smothered and it can't feed. Definitely not a good beginner's choice
