My tiger tail cucumber has been doing well for at least 3 years. Both the sand sifting sea star and fighting conch that I tried didn't last a year. However I don't feel that the cucumber does much to keep the sand bed looking clean. What I have found that helps is a healthy abundance of micro fauna living in the sand bed. Spaghetti worms and bristle worms both do an exceptional job... so be careful what you choose. Pick something that eats algae and detritus but leaves the bugs and bacteria alone (if such a thing exists). Or don't buy anything at all and just give it time to mature. Perhaps get some cups of sand from other reefers in your area to increase the diversity in your sand bed.
