I used a lettuce nudibranch for my turf algae and he worked great till it was all gone and he starved himself. Be careful putting any kind of slug in your tank because some of them can take down an entire system if they die. I know the lettuce guy is fairly harmless once they die. Low toxin levels. You'll probably have to order him online because slugs breed in the spring, they're probably not available in most stores .
