Hi Guys! About a week and a half ago I added 6 Astrea Snails and 6 Blue Leg Hermits to my 30 Gal tank which are the first inhabitants of my tank. The snails and hermits are doing a great job at keeping the upper part of my rock work clean but the bottom base rocks and sand are turning brown and hairy. The blue hermits tend to stay on the upper parts of my rock and not get on the sand. I know theres several types of snails that are good for the sandbed, cerith and nassarius, and that you can also add an emerald to help pick at the rocks. What is you guys experience with those types of snails or is there something else that is better at stirring the sand bed? I thought about a diamond goby but I am currently not using a lid and I know they can be jumpers. Although my tank is a tall so he would have to swim up quite a ways to jump. I like emerald crabs but I am kind of afraid to add one. I had a friend whose emerald knocked his rocks over and would constantly move things around and mess with corals, which I am not sure I want to deal with.
