Freshwater crabs are intriguing creatures that can add a splash of color and excitement to your aquarium. With their vibrant shells and lively movements, these crustaceans become an eye-catching feature. It’s important to provide them with suitable hiding spots and ensure the tank is properly secured, as some species are skilled escape artists.

It’s crucial to carefully research and select appropriate jellyfish species, ensuring you can meet their specific needs for water quality and feeding.
