The freshwater fish’ diet only depends on what is in its habitat and the nutrients that they provide for them and therefore it causes that the feeding habits of the fish are very diverse and can vary according to the case. Their skin like other vertebrates contains special characteristics, since most freshwater fish are covered by scales which are what allow them to resist the different temperature changes to which they are continuously exposed.Īlthough not all species have scales on their bodies some freshwater fish species contain another type of structure very similar to scales that performs the same function. The tail represents another extra complement to its anatomy, since in the company of the dorsal fins in the trunk area are the ones that provide all the movement to freshwater fish, allowing them to reach the necessary speed to move along and width of the waters where they coexist. It’s worth mentioning that their trunk or abdomen houses most of their organs where a pair of fins can also be seen which give them greatest possible mobility in the water. Their head contains branchial areas which allow them to store the greatest amount of oxygen and to be able to breathe properly in the water. They have the same body aspect as most vertebrates, their characteristics may vary depending on the species to which they belong, their body is made up of a head, trunk or abdominal area and a tail. Since not all waters are the same, some are denser than others with which each type of fish adapts little by little. In the case of the freshwater fish, their anatomy depends on the water where they are developing. Today there are smaller and more varied species depending on the families to which they belong. Since these beginnings little by little the structure of such fish changed, and different investigations and studies have shown that their anatomy has been altered over the years. Their evolution is a subject that is still under discussion by many experts, since an exact time is not yet known in which it demonstrates the beginnings of the freshwater fish. In their anatomy you can also see some scales throughout their body that allows them to have better mobility. They have special gills that help them regulate their temperature in the water, their body is usually covered by scales that regulate low temperatures. This type of habitat is somewhat small but spacious enough for them to survive comfortably. The albino form is common in the aquarium trade.As we have previously mentioned, freshwater fish are living beings that develop mainly in rivers, lakes, and lagoons. Needs to be kept in a group of five or more. nigriventris prefers bottom feeding on Tubifex, but its main diet consists of algae. Parasitizes on mouth brooding cichlids by laying their eggs in the cinclids eggs where they are then cared for by the cichlid and starving/ eating the cichlid fry (similar to cuckoo bird hence the name) requires mouth brooding cichlids to breed, they are otherwise good tank mates for cichlids from lake Tanganyika Smaller, Peaceful and when disturbed can shed a layer of mucus from its skin in order to distract would be predators The largest of the shovelnoses, this catfish grows huge and will need a 450 US gallons (1,700 L) min when mature. fasciatum.įirewood catfish, (planiceps) shovelnose catfish Their mouths look small, but may eat smaller fish, as they can open their mouths very wide. These catfish are very appealing when small, but may grow somewhat large. Spotted pimelodus, pictus, pictus catfish Needs at least a 2,600 US gallons (9,800 L) tank when mature, even though this does not provide them with the space to show their natural behaviour. One of the most popular Hypancistrus species.Ī peaceful algae eater. Other related fish also share this common name. Leopard sailfin pleco, clown sailfin pleco One of the several fish sold under this name. One of the several fish sold under this name there is also an albino variation. Several species of panaque are popular aquarium fish.Ĭommon pleco, suckermouth catfish, Amazon sailfin catfish Many species of this fish exist, but are not yet officially identified the three common aquarium species are known as L-018, L-081, and L-177. Males and female both have long "bristles" on their nose, the males having distinctly longer ones. The bristlenose genus has at least 59 identified species and many others yet to be named. Threestripe corydoras, leopard catfish, false julii cory Peppered corydoras, salt and pepper catfish Catfish Armored catfish including Aspidoras, Brochis, Callichthys, and Corydorasīrochis is often synonymized with Corydoras.
