The Red/Black Calceo Shrimp (Caridina spinata var.) is a striking and highly sought-after Caridina shrimp from the ancient lakes of Sulawesi, Indonesia. Displaying a bold red and black banded pattern, they are a showpiece invertebrate for the dedicated shrimp keeper. Their unique appearance and fascinating behaviour make them a true centrepiece of any Sulawesi biotope or species tank.
