Hi,
My sandbed cleaning crew consists of Cerith snails, strombus snails and 1 tiger sea cuke.
The good thing abt the tiger cuke is that it does not climb up the glass and so unlikely to get caught in any powerhead. Dun see this guy much, only comes out at night, sort of the night shift team..
but can see the result of his hard work - balls of clean sand
Cheers
