Fish breathe with their gills, and they need a constant supply of oxygen. Gills sit under the operculum. This is called the gill slit.

So fish still need oxygen to live, they just get it from the water instead of the air. Where do they live? Fish live in nearly every large body of water in the world including streams, rivers, ponds, lakes, and oceans. Some fish live on the surface of the water and some live in the very depths of the ocean.

Fishes live in virtually all aquatic habitats. Different species of fish are adapted for different habitats: rocky shores, coral reefs, kelp forests, rivers and streams, lakes and ponds, under sea ice, the deep sea, and other environments of fresh, salt, and brackish water.

Fish can easily swim in water as their structure and internal organs are all conducive to it. Explanation: Fishes have gills with which they can breathe and extract out oxygen from water. Their body shape is such that they can swim with the least resistance in the water.

Swim bladder

Fish urinate either through their gills or through a “urinary pore.” The latter eliminates urine that has been filtered via the kidneys. Saltwater varieties excrete most urine through the gills, while freshwater fish do so through the urinary pore. Freshwater fish have to get rid of all the water they take in.

The upper jaw is fixed and will not move. The mandible is the moveable part of its jaw. Locate and label the upper jaw or maxilla and the lower jaw or mandible.

Fish swim bladders are perfectly edible, nutritious, and beautifully interesting. Talk to a chef about nose-to-tail eating, and they’ll tell you it just makes sense.

Swim bladder disease, also known as swim bladder disorder, is not a fatal condition in aquariums. In the wild, it could cause the death of fish because a fish will not be able to compete for food, but in aquariums, there is no need to.

Symptoms of Swim Bladder Disorder Fish suffering from swim bladder disorder exhibit a variety of symptoms that primarily involve buoyancy,1 including sinking to the bottom or floating at the top of the tank, floating upside down or on their sides, or struggling to maintain a normal position.

As it is not actually a disease, swim bladder problems are not contagious. If one fish has a problem, your other fish won’t “catch it”. However, they may still be at risk of developing similar problems.

You could simply microwave the peas for 10-15 seconds and then remove the shell prior feeding it to your fish. How long can a goldfish live if the disease is not treated? If you don’t treat the fish it won’t live for more than up to a few weeks, as it would just get worse.

Swim bladder disorder is when a betta has a disrupted swim bladder. This can be caused by overfeeding or it can occur with younger bettas when their swim bladders are not yet fully formed. This disorder is commonly seen in betta keeping and it usually just goes away by itself.
