The term shrimp is used to refer to some decapod crustaceans, although the exact animals covered can vary.

Used broadly, it may cover any of the groups with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata.

In some fields, however, the term is used more narrowly, and may be restricted to Caridea, to smaller species of either group, or to only the marine species.

Under the broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails (abdomens), long whiskers (antennae), and slender legs.

Any small crustacean which resembles a shrimp tends to be called one.

They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly.

Crabs and lobsters have strong walking legs, whereas shrimp have thin fragile legs which they use primarily for perching.

Algae (singular alga) is an informal term for a large, diverse group of photosynthetic organisms which are not necessarily closely related, and is thus polyphyletic.

Included organisms range from unicellular genera, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length.

Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem, which are found in land plants.

The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and the stoneworts.

Cichlids are fish from the family Cichlidae in the order Perciformes.

Cichlids are members of a suborder known as Labroidei, along with the wrasses (Labridae), damselfishes (Pomacentridae), and surfperches (Embiotocidae).

This family is both large and diverse.

At least 1,650 species have been scientifically described, making it one of the largest vertebrate families.

New species are discovered annually, and many species remain undescribed.

The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.

Cichlids are popular freshwater fish kept in the home aquarium.

An aquarium (plural: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which water-dwelling plants or animals are kept and displayed.

Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles such as turtles, and aquatic plants.

The term, coined by English naturalist Philip Henry Gosse, combines the Latin root aqua, meaning water, with the suffix -arium, meaning "a place for relating to".

The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as their numbers do not grow too large.

The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, The Aquarium: An Unveiling of the Wonders of the Deep Sea in 1854.

Tropical fish are generally those fish found in aquatic tropical environments around the world, including both freshwater and salt water species.

Fishkeepers often keep tropical fish in freshwater and saltwater aquariums.
