You can scrape the front portion of the glass below the sand line without risking a spike...be carefull..dont go to far away from the glass, and dont go to fast as to stir it up.
2(no more than that) fighting conchs, and about 8 or so nassarius snails and about 8 maragrita snails(aka stomatella, for the rock work). MAYBE a few more turbos to hlep keep up with the glass
Why do most of my hermits and snail stay on the LR? Nobody seems to interested in my glass I have cerith and turbo snails and hermits. Want to get a fighting conch. Are they reef safe?
