The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.
The leopard gecko or common leopard gecko is a ground-dwelling gecko native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal.

Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. They are also important primary consumers that relay the biomass and energy from photosynthetic autotrophes up into the food web, as well as protecting the aquatic ecosystem against algae blooms.
Lysmata is a genus of shrimp in the infraorder Caridea, the caridean shrimp. The genus belongs to the family Lysmatidae. Lysmata are popular ornamental shrimp in the marine aquarium trade for their bright color patterns, interesting behaviors, and ability to control certain aquarium pests such as sea anemones of the genus Aiptasia. They are known to command high prices on the pet market.
Neocaridina is a genus of atyid shrimp, containing 26 species as of March 2023. Members of the genus are distributed across East Asia including China, Korea, Japan, and Taiwan. Like many other Atyid shrimps, they live in freshwater habitats.
Caridina dennerli is a small species of freshwater shrimp from Sulawesi (Indonesia) that grows up to 2.5 centimetres (1.0 in) in length. It takes its name from the German company Dennerle, which supported the expedition that led to the scientific description of the species. It is popularly known as the cardinal shrimp or Sulawesi shrimp in the aquarium trade.
Neocaridina zhangjiajiensis, known as the pearl shrimp in the aquarium hobby, is a freshwater shrimp. Multiple breeds were bred in Germany for the aquarium trade.
Caridina mariae, commonly known as the tiger shrimp, is a variety of freshwater shrimp from Southeast Asia that are popular in hobby aquariums. The natural coloration of the shrimp isa semitransparent body, with dark brown to black blotches on the carapace, and dark brown to black "tiger" stripes along the posterior part of the carapace and along the first six abdominal segments. Variations of the species may also have orange eyes, and orange highlights in the tail fins. There is also a lack of dark markings on the tail fan
The bee shrimp, is a species of small freshwater shrimp in the family Atyidae. It is native to Taiwan. These shrimp are scavengers, and eat small pieces of decayed vegetation and algae. Bee shrimp have a life span of about 18 months. They enjoy a temperature in the 70 to 78 °F range. Many modern versions of bee shrimp are selectively bred for their characteristics.
Red Devil Vampire Crabs are decapod crustaceans part of Brachyura.
Caridina spongicola is a small species of freshwater shrimp from Sulawesi (Indonesia) that reaches 0.64 to 1.27 cm in length. In the wild it strictly lives on an undescribed species of freshwater sponge, making it one of only two known commensal species of freshwater shrimp. It is popularly known as the harlequin shrimp, and also sometimes Celebes beauty shrimp or sponge shrimp in the aquarium trade. It is often confused with Caridina woltereckae, a larger and more contrastingly colored species found in the same region as C. spongicola.
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, semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
Atyoida serrata is a species of freshwater shrimp of the family Atyidae and genus Atyoida. The species lives in the Vungu, Umgeni, and Mtamvuna rivers in South Africa, as well as the Langevin River on Réunion Island.
Caridina typus, also known as the Australian Amano Shrimp, is a species of amphidromous atyid shrimp. It was first described by H. Milne-Edwards in 1837. It has a broad distribution in tropical freshwater habitats in the Indo-West Pacific region, with its western range extending to eastern Africa and its eastern range extending to Polynesia. It is commonly found in rivers and streams in coastal areas or on islands. C. typus is known to play a role in sediment distribution and shredding leaf litter, manipulating the environment using their pereiopods and setaceous chelae. The species is also an important component of the food web, both as scavengers and as prey items, and is considered a keystone species for the stream ecosystems it inhabits. According to Choy and Marshall, the species can be characterized by a "short, dorsally unarmed rostrum, the presence of epipods on the first four pairs of pereiopods, and the presence of an appendix interna on the endopod of the first pleopod of both sexes." It can be kept in captivity by aquarists as pets.
Caridina tetrazona is a species of freshwater shrimp native to the Wanshan islands in Guangdong Province, southern China. It was described from specimens collected on Dawanshan Island, where it is found alongside Caridina serrata. The name 'tetrazona' refers to the four banded color patter found in this species.
