== == Your goldfish most likely has a swimbladder disorder/disease. This happens when the swim bladder, a gas filled organ that controls the fish's bouyancy by inflating or deflating, is unable to control itself and causes the fish to either stay at the bottom of the tank, float helplessly at the top, bob-around head first at the bottom, swim on its side, or swim upsidedown. A swimbladder problem can be caused by consipation, bacterial infection, poor water quality, physical damage to the swim bladder, or physical deformity of the swim bladder. This condition is sometimes hard to treat because its often hard to diagnose the cause before its to late. The first step to take with a fish that has a swim bladder disorder is to test the water quality of your tank. It is usually a good idea to move the affected fish into a 5-10 gallon hospital tank for observation/treatment to ensure that the other fish do not become sick also. A good first act of treatment for an unknown cause of a swim bladder disorder is to try feeding the fish a shelled thawed or cooked unsalted green pea (the green pea is a laxitive and will relieve your fishes swimbladder problem if it is constipated). If this does not help you may want to start the fish on a antibacterial medication. Do frequent water changes at this time because having good water quality will offer relief for the affected fish. Also lower the tanks levels so that is is about 1/2-2 inches above the fishes dorsal fin (this reduces pressure on the swim bladder causing the fish much relief).If the fish looks swollen that is often either the beginning stages of dropsy or a sign of constipation. If dropsy is suspected than you would want to start the fish on antibacterial medicated food soon! Often fish do not recover from a bacterial infection of the swim bladder. Bacterial infections will usually result in dropsy- which is almost impossible to cure.
they try to find the way so the swim sideways so if they go foreword they will hit the glass and could kill them. they go sideways so they ony hit the side of them. fish are smarter than what we are . they have to get use to the light change
Whales are not fish. Fish move their bodies sideways when they swim; whales move their bodies up and down.
A catfish would be an example of a fish that can swim.
Your betta fish may be laying sideways due to swim bladder disorder, which can be caused by overfeeding, poor water quality, or stress. It is important to address the underlying cause and provide proper care to help your fish recover.
no i would not eat fish or swim in those lakes.
Then the fish would swim away.
swim bladder is what helps the fish stay afloat without the swim bladder a fish would simply sink duhhh
A very sick one. All fish are able to swim. Otherwise, It would not be one!
Without fins, fish would not be able to move around (swim) and live.
they swim all ways..their is not forward backwards or sideways....
Swim, eat and eat and rest and swim and then eat and so on.
It may be because the main source of light is from the side and the fish is trying to balance itself and make sense of the light source in its autonomous systems. It is more likely however that the fish has a swim bladder problem. If this is so, then to the best of my knowledge there is no reliable cure/treatment and the fish is best euthanased.
