I found a different kind of snail in my tank last night when I was doing a water change. I have no clue if it was under the rocks, on the rocks, on the glass, on a decoration or where when I started but I found it on top of the rocks and promptly took it out with the intent of taking its picture to get an id on it.
Well I must be an idiot because the stupid thing ran away or I lost it so hopefully a discription will answer my question.
The shell was cone shaped and less than a cm long, not quite a bleachy white but not truly a shade of brown either. The opening was about 1/3 the length of the shell. I think it might be an assasin snail but I don't know if there are any look alikes that are found in aquariums. I know I have normal evil snails that eat plants and make a mess so I bought 3 yo yo loaches. I'm not sure though if they leave the shells when they eat snails but I have quite the collection of empty snail homes in my tank now.
