Over the last few months I've been running into an issue of my 4 hermit crabs killing my snails in my 65g reef, and this past week it got back enough that I just got rid of the crabs after they collectively killed 2 adult trochus snails and 4 cerith snails in the span of 2 days, effectively halving my CUC (I have several empty shells in my tank and the hermit crabs never take over the shells of the snails they kill so I doubt it's related to needing a new shell).
Point is, I now have a much smaller CUC consisting of about 5 trochus snails, 1 tiger conch, 3 nassarius snails, and 2 cerith snails. For general algae control I was planning on just beefing up the cerith snail count and maybe getting a couple more trochus, but on the carnivore/detritus side of things I have nothing to deal with the rockwork. My conch and nassarius snails do a great job keeping the sand bed clean but they don't really touch the rocks. I was thinking of a shrimp but I've heard more than enough stories about them harassing coral to not want one. Are there any really good CUC members I'm overlooking that could solve my issue?
