P. paludosus in a freshwater aquarium. Feeder shrimp, ghost shrimp, glass shrimp, grass shrimp, river shrimp or feeder prawns are generic names applied to inexpensive small, typically with a length of 1 to 3 cm (0.39 to 1.18 in), semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
Palaemonetes paludosus, commonly known as ghost shrimp, glass shrimp, and eastern grass shrimp, [2] [3] is a species of freshwater shrimp from the southeastern United States. [4] They can be considered a keystone species based on the services they provide to their habitat. [2] They are also popular in the domestic aquarium business. [5]
Neotrypaea californiensis (formerly Callianassa californiensis), the Bay ghost shrimp, is a species of ghost shrimp that lives on the Pacific coast of North America. It is a pale animal which grows to a length of 11.5 cm (4.5 in). One claw is bigger than the other, especially in males, and the enlarged claw is thought to have a function in mating.
Glass shrimp are commonly used as bait by freshwater anglers, being taken with dip nets or common box net bait traps. [4] Shrimp are also used as live food for aquarium fish of sufficient size and are themselves kept as aquarium specimens either by themselves or with smaller fish.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Like all caprellid amphipods, Caprella mutica are characterized by slender bodies and elongated appendages. Their skeletal appearance gives rise to the common names of "skeleton shrimp" or "ghost shrimp", [4] and, coupled with their distinctive upright feeding posture, give them a striking resemblance to stick insects and "starved praying mantises". [5]
Juvenile shrimp will molt more frequently, as they must shed their exoskeleton as they grow. This discarded exoskeleton should be left in the tank, as the shrimp will eat it to recover the valuable minerals it contains. Pregnant N. davidi shrimp tend to hide in the dark. If they feel endangered by predators, they will abandon their eggs.
Palaemon is a genus of caridean shrimp in the family Palaemonidae. [ 2 ] Some species, including Palaemon macrodactylus and Palaemon orientis , can inhabit fish ponds where they compete with fish for food and can therefore be considered pests.
