A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium. [2] Swim bladder disease is a very common illness within aquarium fish that results in the bladder not functioning properly causing the fish to swim upside down.
The stop-start motion provided by the jets, however, continues to be useful for providing bursts of high speed – not least when capturing prey or avoiding predators. [14] Indeed, it makes cephalopods the fastest marine invertebrates, [15]: Preface and they can out accelerate most fish. [16]
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy.

Ram ventilation [11] is the process in which at higher speeds, the remora uses the force of the water moving past it to create movement of fluid in the gills. At lower speeds, the remora will use a form of active ventilation, [11] in which the fish actively moves fluid through its gills. In order to use active ventilation, a fish must actively ...
2. Flathead Catfish: They’re most common in large rivers and lakes, and they primarily feed on live fish. Because of their large size and appetite, flatheads have contributed to the declines of ...
Able to spend longer times out of water, these fish may use a number of means of locomotion, including springing, snake-like lateral undulation, and tripod-like walking. The mudskippers are probably the best land-adapted of contemporary fish and are able to spend days moving about out of water and can even climb mangroves , although to only ...
The goal of quarantine is to prevent problems in the main tank due to sickness. A quarantine tank should be used before to introduce any newly acquired animals in the main tank and to treat fish that are already sick. By doing this, the aquarist can avoid the spread of the disease and make it easier to treat the fish. [1]
Ciguatera fish poisoning (CFP) is very common from the exposure of algal blooms. Water-borne diseases are also present as our drinking waters can be contaminated by cyanotoxins. If the HAB event results in a high enough concentration of algae the water may become discoloured or murky, varying in colour from purple to almost pink, normally being ...
