My snail population has dwindled since I got my cleaner package 18 months ago. Now I'm starting to notice some green algae growing on the rocks, so whichever group was responsible for that has apparently fallen below critical mass.
But the problem is I don't know which snail does what. I think I started with turbo, margarita, trochus and cerith -- which type should I reload on to get some rock grazers?
