nitrates

Any salt or ester of nitric acid, and the end product of the portion of the nitrogen cycle taking place in most closed aquarium systems (the conversion of nitrates to nitrogen gas in natural systems is carried out by anaerobic microorganisms not normally present in sufficient numbers in aquaria, though this process can be induced by installation of a nitrate reactor). While nitrates are less toxic than ammonia or nitrites, they are still potentially harmful to fishes and other aquatic organisms if allowed to accumulate unchecked, and must therefore be diluted via regular water changes. Aquatic plants also help since they are able to metabolise nitrates to an extent.

Used in 20 profiles

nitrites

A salt or ester of nitrous acid. Produced in aquaria via metabolisation of ammonia by nitrifying bacteria of the genus Nitrosomonas, and toxic to fishes if present in sufficient concentrations, but in a mature system is further converted into less-harmful nitrates by other bacteria of the genus Nitrospira.

Used in 1 profile

oak leaf

Leaf of the tree and shrub genus Quercus. Dried and used in aquaria to simulate certain natural conditions, especially those typical of blackwater habitats.

Used in 43 profiles

oesophagus

original description

Used in 51 profiles

osmoregulation

Active regulation of osmotic pressure, especially in the body of a living organism or cell, in order to prevent the body fluids from becoming too diluted or concentrated.

ossicle

Small bone, especially any of the three small bones in the inner ear of vertebrates.

Used in 4 profiles

pathogen

Any agent causing disease or infection, especially a bacterium, virus, or other microorganism.

peat

A compressed accumulation of partially-decomposed, chiefly vegetable matter typically found in certain marshes, bogs, and peat swamp forests throughout the world. It forms via breakdown of various plants and other organic materials in water when full decomposition is prevented due to localised acidic, anaerobic conditions. As a result of this somewhat specific nature the organisms inhabiting peaty environments are often stenotypic and found nowhere else. Peat can be used as a fuel when dried and thus has industrial importance in some countries. Also used in aquaria, especially in order to simulate blackwater habitats, either in pure, artificially-granulated or liquid extract form.

Used in 268 profiles

pelvic disc

Disc-shaped modification of the pelvic fins, which are often fused, used to adhere to surfaces via suction. Present in certain fishes, especially members of the family Gobiidae. Also known as sucking disc.

Used in 31 profiles

perforation

A hole or pattern of holes made by, or seeming to be made by, piercing or boring, especially if occurring in a line or series.

Used in 1 profile

phosphates

Any salt or ester of phosphoric acid. The presence or addition of excessive phosphates in aquatic ecosystems can have significant ecological effects such as eutrophication, and they are one of the primary contributors to algal growth in aquaria if allowed to accumulate. Conversely, they may be actively added to heavily-planted set-ups in the form of liquid or other supplements in order to encourage plant growth.
