Oh yeah forgot about the sand sifters..... With all the intense thinking about philosophical and mathematical dilemnas i lost sight of my goal
I don't know much about sand beds. I would think for them to be healthy and active that you do need sand sifters. But specific sand sifters. In that sense only snails would be applicable. They will dig in the sand but will not eat the life contained therein, such as cerith snails and nassarius snails.
Starfish, gobies, etc, etc would not benefit a sand bed due to their feeding nature. They would sift through the sand and consume any resources that are in it. So while the sand may harbor beneficial bacteria it can't sustain any macro?life that may be growing in it due to the predatory nature of those sifters.....
YAY 1000 posts. Ok now i think im going to go to sleep cause my brain hurts. I'll be back to answer more daunting questions later tonight
