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. This disorder can be due to multiple factors such as physical abnormalities, environmental, mechanical, or in some cases due to fishes being inbred.
The Mochokidae are a family of catfishes (order Siluriformes) that are known as the squeakers or known as upside-down catfish (although not all species swim upside-down). There are nine genera and about 200 species of mochokids. [1] All the mochokids are freshwater species originating from Africa. [2]
Scientists do not know. When fish swim in circles and even turn upside down, it's called whirling. "Some fishing guides started seeing these whirling fish around Big Pine Key," Mike Parsons, a ...
The more objects around the fish, the more they tend to swim upside down. [4] When close to an object, the fish puts its ventral side closest to the object. [4] It rarely swims in the middle of the water, preferring to swim either at the bottom or at the surface. [6] By swimming upside down when it feeds, [7] it can readily catch prey at the ...
The porcupine fish (as Diodon antennatus) is mentioned in Charles Darwin's famous account of his trip around the world, The Voyage of the Beagle. He noted how the fish can swim quite well when inflated, though the altered buoyancy requires them to do so upside down.
Occasionally C. macracanthus will exhibit erratic swimming patterns, such as swimming on their sides or upside down. This is not usually a sign of illness, however, and the fish will normally return to normal behaviour almost instantly. As C. macracanthus is found in riverine environments it is able to cope with good flow rates of water in the ...
In the wild, it swims upside down with its belly facing upward, which explains its darker colors on the underside and lighter colors on the dorsal side. [1] In captivity, however, the fish sometimes stops swimming upside down and its color pattern reverses, so that it is dark on the back and light on the underside. [ 1 ]
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.
