The leaves turn a shade of pink or orange as they grow closer to the light source. Many people find that this plant produces too many new shoots and eventually becomes a nuisance. It is a good plant for quickly filling a planted aquarium, using its new shoots to propagate new plants in a matter of days. [4]
Fine bubble diffused aeration is able to maximize the surface area of the bubbles and thus transfer more oxygen to the water per bubble volume. Additionally, smaller bubbles take more time to reach the surface so not only is the surface area maximized but so are the time each bubble spends in the water, allowing it more opportunity to transfer ...
Elodea is a genus of eight species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog's-bit family (Hydrocharitaceae), Elodea is native to the Americas [1] and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities.
In the aquarium, B. heudelotii requires water temperatures of 20–28 °C and moderately acidic ('soft') to neutral water with a pH range of 5.0–7.0, [6] but tolerates a wide range of light levels. It does best in flowing water. [7] [8] [3] This species is often used as a midground specimen plant in tropical freshwater aquaria. Propagation is ...
Dwarf gourami bubble nest made of bubbles, floating plants and plant parts which were torn from a Hydrocotyle by the gourami male.. Bubble nests, also called foam nests, are created by some fish and frog species as floating masses of bubbles blown with an oral secretion, saliva bubbles, and occasionally aquatic plants.
Hygrophila difformis, commonly known as water wisteria (though it is not closely related to true wisteria), is an aquatic plant in the acanthus family. It is found in marshy habitats on the Indian subcontinent in Bangladesh, Bhutan, India and Nepal. It grows to a height of 20 to 50 cm with a width of 15 to 25 cm. [1]
Shinnersia rivularis, known as the Rio Grande bugheal [2] or Mexican oak leaf plant, is an aquatic plant native to Texas, Coahuila, and Nuevo León. It is classified in tribe Eupatorieae within family Asteraceae. [3] [4] [1] [5] It is thought to be related to two other aquatic genera in this tribe, Sclerolepis and Trichocoronis. [6]
Many water beetles carry an air bubble, called the elytra cavity, underneath their abdomens, which provides an air supply, and prevents water from getting into the spiracles. [2] Others have the surface of their exoskeleton modified to form a plastron, or "physical gill", which permits direct gas exchange with the water. Some families of water ...
