Due to the artificially limited volume of water and high concentration of fish in most aquarium tanks, communicable diseases often affect most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental fish in a tank.
Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed. Common aquarium diseases include the following:
The gas bubble disease may cause floating problems due to the excessive amount of gas in their bodies, ultimately leading to upside-down swimming and death. [3] Gas bubble disease may also occur in humans and is commonly known as decompression sickness. It generally occurs in divers when they resurface without using proper decompression procedures.
A planted reef aquarium filled with Bladed sand moss (Caulerpa prolifera) A seagrass aquarium housing several seagrass meadow inhabitants. Aquatic plants are used to give the aquarium a natural appearance, oxygenate the water, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also ...
Fine bubble aeration is an efficient technique of aeration in terms of oxygen transfer due to the large collective surface area of its bubbles. Fine bubble aeration is an efficient way to transfer oxygen to a water body. [8] A compressor on shore pumps air through a hose, which is connected to an underwater aeration unit.
A fish's hypoxia tolerance can be represented in different ways. A commonly used representation is the critical O 2 tension (P crit), which is the lowest water O 2 tension (P O 2) at which a fish can maintain a stable O 2 consumption rate (M O 2). [2]
A spherical airstone at the Osaka Aquarium alongside a trio of red stingray pups, Hemitrygon akajei. An airstone, also called an aquarium bubbler, is a piece of aquarium furniture, traditionally a piece of limewood or porous stone, whose purpose is to gradually diffuse air into the tank, eliminating the noise and large bubbles of conventional air filtration systems, and providing other ...
The bell of the jelly blubber is spherical in shape, and its feeding structures make up a greater proportion of its body than in many other species of jellyfish. [5] Because of their unique body shape, C. mosaicus are known to utilize jet propulsion, triggered by the contracting and relaxing patterns of their bell.
