I'm fairly certain these guys are not NZMS due to their size, but wanted to get second opinions before putting them in my 55g tank! I have way too many little snail species to be able to separate them out if I accidentally get something bad in there. Mostly what's tripping me up is no notable ridges, but I don't know if that's something that could have been from low pH or not.
