sera guide - Shrimps and crayfish

4 Shrimp species Dwarf shrimps A crustacean group consisting of many small (often only up to 4 cm / 1.6 in.) shrimp species that is very popular among aquarists. Dwarf shrimps graze off algae and other periphyton from surfaces such as plants or rocks. The decorative and interesting animals are usually very peaceful and can be kept in large groups. They can also be kept together with calm fish and other aquarium inhabitants. Longarm prawns These shrimps have rather long claws. Some species grow very large, therefore some of them may also eat fish and other crustaceans. Furthermore, their distinct territorial behavior may cause fighting with other members of their own species. Smaller species such as the Pearl shrimp (Macrobrachium cf. banjarense) or the Riceland prawn (Macrobrachium lanchesteri) are usu- ally more peaceful and require less space. Fan shrimps These animals have long bristle brushes at the ends of their first leg pair that they can extend like a fan. They use these fans to filter floating food particles (herbal and animal plankton) from the water current. Fan shrimps like to sit on coarse or solid surfaces where they can get a hold in the current.
