Description
The Pomacea urceus is one of the largest species of apple snail, known for its thick, heavy shell and striking appearance. Native to slow-moving waters in South America, this freshwater snail is a rare and fascinating addition to large tropical aquariums.
With a shell that can reach up to 15 cm in diameter, P. urceus stands out as a true display invertebrate. Its slow, deliberate movement and peaceful nature make it a great choice for keepers looking to add something unique to their tank. Unlike some smaller apple snails, Pomacea urceus grows large, lives long, and is best suited for spacious, well-maintained aquariums.
