Tylomelania sp. (Sulawesi Elephant Snail)
I got these about a week ago. They aren't as amazing as some of the yellow-bodied species but are still pretty interesting. I have yet to create a setup where they can be photographed underwater - but when I do I will post some pictures.
If anybody has any of this, or other species to spare please get in touch. I am very interested in keeping and breeding other species.
