I have a got tropical fish not marine, i have just noticed about 50 snails, i think they are snails. long, light brown cones with little brown spots, they range from 3mm to 1 cm in length. They are alive because they are moving and i can see there heads popping out. It looks like they are coming up from below my gravel. They have all appeared together or i have not noticed them before, i check my tank everyday and have never seen them before. Will they damage my fish, what are they, where did they come from, should i remove them?
