Aquarium in the context of "Algivore"

Cyanide fishing is a specific method of collecting live fish, mainly for use in aquariums, which involves spraying a sodium cyanide mixture into a habitat in order to incapacitate the fish there. This practice affects not only the target population, it also has negative and damaging effects on many other marine organisms, including coral and coral reefs.

A pet, or companion animal, is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock, or a laboratory animal. Popular pets are often considered to have attractive/cute appearances, intelligence, and relatable personalities, but some pets may be taken in on an altruistic basis (such as a stray animal) and accepted by the owner regardless of these characteristics.

Two of the most popular pets are dogs and cats. Other animals commonly kept include rabbits; ferrets; pigs; rodents such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; birds such as parrots, passerines, and fowls; reptiles such as turtles, lizards, snakes, and iguanas; aquatic pets such as fish, freshwater snails, and saltwater snails; amphibians such as frogs and salamanders; and arthropod pets such as tarantulas and hermit crabs. Smaller pets include rodents, while the equine and bovine group include the largest companion animals.

The term coldwater fish can have different meanings in different contexts.

• In the context of fishkeeping, it refers to ornamental fish species that tolerate the temperatures of a typical indoor aquarium well and do not require a heater to remain active, as opposed to tropical fish whom need a heater to survive in the room temperatures of temperate climates;
• In the context of ecology and fishing, it refers to fish species that prefer to inhabit waterbodies or depth zones with much lower temperatures than the average temperate water. Salmonids (e.g. salmon, trout, char and graylings) are a classic example of such types of fish.

The Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), are a superfamily of weakly electric fish in the order Osteoglossiformes native to Africa. It is by far the largest family in the order, with around 200 species. Members of the family can be popular, if challenging, aquarium species. These fish have a large brain size and unusually high intelligence.

They are not to be confused with the marine and brackish-water callorhinchid elephantfish (family Callorhinchidae) of Southern Hemisphere oceans.

Escapology is the practice of escaping from restraints or other traps. Escapologists (also called escape artists) escape from handcuffs, straitjackets, cages, coffins, steel boxes, barrels, bags, burning buildings, fish-tanks, and other perils, often in combination.

The Nanay River is a river in northern Peru. It is a tributary of the Amazon River, merging into this river at the city of Iquitos. The lower part of the Nanay flows to the north and west of the city, while the Itaya River flows to the south and east. Other nearby settlements on the Nanay River include the villages of Santo Tomás, Padre Cocha, and Santa Clara. During periods when the river is low, the many beaches along the Nanay are popular destinations. The Nanay belongs entirely to the lowlands, and is very crooked, has a slow current and divides into many canos and strings of lagoons which flood the flat, low areas of country on either side. It is simply the drainage ditch of districts which are extensively overflowed in the rainy season. Captain Archibald Butt USN, ascended it 195 mi (314 km), to near its source. A part of the Nanay River flows through the Allpahuayo-Mishana National Reserve.

The Nanay is a blackwater river and it has a high fish species richness, including several that are well known from the aquarium industry. Some of these, notably green discus, are the result of accidental introductions that happened in the 1970s.

Triggerfish are about 40 species of often brightly colored marine ray-finned fishes belonging to the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish (Canthidermis maculata), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.

The National Aquarium, Washington, D.C., was an aquarium in Washington D.C. It was located in the Herbert C. Hoover Building (owned by the General Services Administration), which is bounded by 14th Street NW on the east, 15th Street NW on the west, Pennsylvania Avenue NW on the north, and Constitution Avenue NW on the south. It was the first free and public aquarium in the United States.

The National Aquarium in Washington, D.C. was smaller than its counterpart in Baltimore, Maryland — a facility also known as the National Aquarium, although independent until the two aquariums signed an alliance in 2003. The Washington aquarium closed on September 30, 2013, after 140 years, the longest continuously operating aquarium in the United States at the time.
