Hey everyone, looking to add some sand dwelling critters to help move the sandbed around better. I current have two conchs, some smaller hermits and quite a few snails but they either deal with my rock, glass or sandbed surface. Normally I'd get a a few nassairous snails but with this being my first time using a larger substrate (crushed coral) I'm unsure if they will be able to bury in there. Any other suggestions like starfish or other inverts would be great. Thanks!
