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. Despite this, many diseases in captive fish can be avoided or prevented through proper water conditions and a well-adjusted ecosystem within the 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:
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.
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.

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 ...
Swim bladder disease, also called swim bladder disorder or flipover, is a common ailment in aquarium fish. The swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy , and thus to stay at the current water depth without having to waste energy in swimming.

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 ...
