Hello R2R reefers! Been noticing these white formations growing on a few of my snails for awhile at first I kinda just let it pass and now everytime I notice it it drives me crazy because I just dont know if its something to be concerned about or good bad whatever, it was just like 2 ceriths that had it also one of those 2 i nicknamed Frankensnail lol he had green and blue neon color formations that would pop out feather dusters pretty neat to watch but these white spots look like sand volcanoes and havent noticed any movement at all from the holes so idk?? Now almost every shell shows some white or alot of white spots or formations, im sorry these pics arent the best my phones camera sucks, ive done search after search online to no avail! Possibly barnacles but from what I can tell those arent as shiny white or gritty like these
