Hi all! My Nicrew gravel vacuum is pretty useless for keeping my sand clean so I'd like to try a living approach. My LFS recommends a diamond sand sifting Goby. R2R recommends a conch. Which one of these is the better option for my 40G? I'm also open to other options if neither of these are appropriate.
Current fish: Frostbite clown, bicolor blenny, exquisite firefish, geometric dwarf perchlet, royal gramma
Future fish: second clownfish, pink streaked wrasse
Current CUC: Collector urchin, mix of dwarf cerith, cerith, astraea and nassarius snails
Future CUC: Please tell me!
