Currently I have about 3-4 nassarius snails from the 9 I got to try to keep my sand shifted, the ones that survived the constant harassment from the multiple wrasses I’ve had specially my Melanurus do an ok job at shifting. 2 strawberry conch and I absolutely love them they are constantly on the move and do a better job at cleaning my sand and moving/shifting it. 2 turbo snails from 3 one died in a crevice I think it couldn’t flip over and the biggest is constantly falling from the glass he’s been lucky so far I have to flip him constantly. 3 astrea nails, these are solid snails constantly on my glass and rocks but spawn a lot and catch many babies everywhere specially my skimmers pump. 1 bubble bee hitchhiker , and a bunch of Stomatella snail also hitchhikers which have grown pretty big in the few years I’ve had them, only see them when the tank is dark, actually they scared me the first time I saw one since he moved so fast after the lights came on. All in my display wished I would’ve bought smaller turbos instead since they are always on my glass and do a good job. I think this is the only pic I have taken of any of my snails I forgot about them once the fish went in lol. I do have a few videos of my nassarius fighting tho lol
