Atya

These shrimps are found in many tropical regions in the Americas, Africa, and Asia, sometimes in brackish water. They are bottom-dwellers that feed on leftover food - both natural and artificial - and fish, and so their ecological role is quite substantial. These shrimps from the Atya genus (particularly Atya moluccensis, native to South-East Asia) are only occasionally found in the aquarium trade. They like lively, well-oxygenated water and are sociable, and so can be kept in small groups. Size: 6-7 cm.
