No, they are still Ramshorn snails, freshwater limpets (Acroloxus) are really small and don't have any shell whorls
I always thought of ramshorns as big snails who held their shells upright and thought I read somewhere that those who had the curly shells but had them horizontally were a different species. I probably misunderstood or more likely completely imagined it
How big are these likely to grow?
I have some in my shrimp tank which never seem to get bigger than about 2-3mm (which makes photographing them a right pain)
