Hawaiian Red Shrimp - Opae ula      Halocaridina rubra

Substrate Scrapers (Atyid Shrimp)

All the shrimp varieties listed below are omnivorous shrimp that consume algae, detritus, microorganisms and dead animals in their natural habitats.  Their claws are especially well suited for grazing microorganisms and algae.  All of these shrimp can be kept in groups since they do not display any aggressive behavior toward each other. Special care has to be taken when planning to keep two or more species together in one tank, since some of the species below can and will hybridize.   Except for the Hawaiian Red Shrimp all the other shrimp are pure freshwater shrimp.  For more information and larger pictures click on the species name.

General Palaemonid Shrimp (normal size claws)

These shrimp are not primarily algae and microorganism eaters, but eat detritus and bigger particulate matter of both animal and plant origin in their natural habitats. In the aquarium they will do great on pellet and flake food and even eat some types of algae (primarily string and hair algae).  Some of these shrimp get quite large, however the shrimp I have listed here will stay small ( usually around 5cm or below) and will not harm any other tank inhabitants. These shrimp have a lot of personality and are fun to watch for hours on end.

Macrobrachium Type Palaemonid Shrimp (Longarm Shrimp)

Macrobrachium (Palaemonidae) shrimp, or short macros,  are probably the most interesting shrimp species available. They are truly the Cichlids of the shrimp world displaying similarly interesting behavior (including territorial behavior).  They are easily recognizable by their robust claws, which are quite long in the males. Many Macrobrachium species are aggressive both toward each other and other species of shrimp and fish, however there are still many that can be kept in pairs or small groups in the home aquarium. Although there are hundreds of Macrobrachium species with attractive coloration, they are not commonly available in the hobby.

Filter Feeding Shrimp (Atyid Shrimp)

The shrimp in this category have specialized claws, which allow them to filter microorganisms and small organic particles out of the water column.  Their sizes range from just an inch to over 6 inches depending on the species. Due to their filter feeding lifestyle these shrimp all need water movement in their environment.  In the aquarium this can me achieved by installing a powerhead or similar pump. The most familiar shrimp to auqarists from this group is the "Bamboo Shrimp" or "Wood Shrimp", Atya moluccensis.
