tigertail cukes clean out stuff from sand bed, I know that they do that that's why I'm getting one!

I had 3 nassarius snails in my old tank and gave them away when I switched back to a nano without a substrate. They didn't do much of anything visually in my tank, they left my sand bed undisturbed and only came out when I fed my fish. They would then glide right over any algae without touching it and go for the food that reached the bottom before a fish got to it. I'm sure they moved the bottom layers of sand around which is good but they never touched the surface of the sand bed. If you're looking for something to clean up the visible area of your substrate I don't think you'll be happy with just these snails, if you want to prevent lower levels of sand from becoming anoxic then they have a bonafide purpose. my 2 cents.

I have a serpant star in my tank, they are very hard as I have abused mine in 3 rather fast new acclimations in the past. They won't clean your sand bed very well but will probe into every corner of your rock bottoms to find every last bit of food and deteris. Great scavangers and seem to leave all inverts and fish alone, just avoid green brittle stars as they have been know to go after sleeping fish.
