My recent 75g tank project has some new critters, atleast a couple hundred of them. I have a few astrea snails, but these look nothing like them. I also have the common hitchhiker snails (tan and brown tiny snails) but these are those either. Nothing has been aded to this tank that I didnt already have other some sand from a buddies tank, and he had the same snails that I do. I asked him about these, and he has no clue. So I took some pics, none came out great cause these lil buggers are tiny right now, the biggest being like 2mm. The tiny ones are solid white, the larger ones are red with white stripes and some look like they have a black growth ring or something. but anyways, a pic is worth a 1000 words....
If anybody has any idea what these are, let me know as I know they are not astreas, my first thought was tulip snails cause they are reddish, but these are not those either.
People that know me, know I am VERY resourcful, and I am coming up with nothing on these.
Something had babies....
