Aquarium Advice Addict
We have recently found that our 20g is full of these. They look and clean just like snail only they don't seem to have shells. They do have raised spots on their backs like they want to have a shell or may be developing a shell. Some are very small but some are almost as big as the turbo snails, only without the shell of course. They do not look like any flat worm pictures I have been able to find, and I have been searching the web for two days looking for a picture of baby snails to see if it's them. You can see their mouths are working just like the snails do. Any good links to some sites that may have pictures.
