What Cucumber to Buy?

The snails would be your safest option. If you are confident that the tank is quite stable and has been aged enough to support a cuke I would highly recommend the black knoby.

I have a pink/black, tiger tail, and the black knoby. The black by far does the best job and is the most active on the sand. I find the tiger tail stays mostly on rock and glass. The pink seems to prefer glass and pre-filter sponges, but does get the sand once in awhile.

Out of them all, the tiger tail is probably the safest when it comes to poisoning issues. That would really depend on the size of the system.
