Hi there,
Variety is by far best. You could get 30 hermit crabs, but obviously they arent going to eat the stuff and do the job the Super Turbs do! My suggestion would be this:
6 REd Legs
6 Super Turbo Snails
6 Nassarius Snails
1 Fighting Conch
1 Cleaner Shrimp
Maybe you could add some cerith snails, a emerald crab or something?
ALl the best,
Tim.
scarlet reef hermits, cerith snails, torchus snails, nassarius snails, strombus snails, etc....but for hermits, only go with the scarlets!
good luck
