We may have big fish, but we also have little crabs. Check out our paludarium filled with adorable vampire crabs the next time you visit us! 🦀

Vampire crabs are communal with other vampire crabs and are easy and cheap to feed. They are semi-terrestrial so they do swimmingly in a planted paludarium (we carry plenty of compatible plants as well as paludariums!). If you're looking for a unique but easy to care for pet, look no further.
