Platidoras striped catfish: content, compatibility, photo-video review
Som Platidoras is one of the most popular som-like fish in our aquariums. Striped catfish is very beautiful.
Along the whole body are wide black and white stripes. This color is especially clearly seen in young individuals, with age, the bands become less noticeable.
In nature, these catfish reach up to 20 centimeters in length, and in the aquarium up to 16 centimeters.
The behavior of platydoras catfish is curious, but it is worth noting that they prefer nightlife, if the environment becomes comfortable, then catfish can actively explore the aquarium during the day.
Catfish are peaceful and hardy. Platiodras will perfectly fit into a common – multi-species aquarium.
Soma belongs to the family of Bronyakovs (Doradidae). The name of the family reflects the essence of this catfish – they have strong skin, a well-developed occipital shield in front of the dorsal fin and bone growths along the lateral line, forming prickly bone shields.
A very interesting fact about this catfish is that he “can sing” them and call them “singing soma”. This is due to the ability of Platydoras and other catfish of the Doradidae family to make sounds. Strumming sounds are produced due to friction of the pectoral fins on grooves in the shoulder joints, and sounds similar to crackling are produced by an elastic spring mechanism that triggers the vibration of the swim bladder.
Of the Bronyakov family, the soma Acanthodoras spinosissimus and Acanthodoras cataphrectus are also singing.
Striped Placidoras tolerates harsh environmental conditions. Despite the fact that individuals of this species are predominantly nocturnal, they often swim out of their shelter in order to explore all corners of their aquarium during the day. They love to dig in the soft river bottom, so be prepared to give them a corner with good sand and gravel.
Platydoras prefer gloomy lighting, so the water surface of the aquarium can be “covered” with floating plants (pistia, duckweed) or you can buy a special lamp for somopodobnyh fish. The aquarium is also equipped with a variety of shelters – voids in snags, clay pots or plastic pipes of various sizes. Plants and Platydoras are completely compatible, but the presence of plants is optional.
Catfish get along well with average-sized non-predatory neighbors. You should not add too small fish to catfish, they can become a snack for him.
The body has a cylindrical swept shape with a flat belly. Females are larger than males, especially when viewed from above.
As mentioned earlier, in the wild, catfish reach 20 cm in length, and sometimes there are also 24 cm individuals. In an aquarium, the average length of adult fish is 15.5 cm.
The average life expectancy of Plateidoras is 20 years. The color of their body can be either dark brown or black, with clearly visible white horizontal stripes that create an alternation of the pattern. The muzzle, the lower part of the head and the front edge of the pectoral fins are white in color.
The older the fish, the less she has the clarity of the pattern. The head of the catfish is large, with large eyes. The mouth is wide, there are two pairs of antennae.
They are located on both sides of the mouth, one on the lower and upper jaw. On the pectoral fins are strong spikes, which the fish is able to straighten hard to the sides, and it can use the internal spikes for striking.
Spikes are often confused in the net of a net, and they are easily pricked. The external similarity between the striped platydoras and the long-nosed catfish, Orinocodoras eigenmanni, often makes it difficult to identify them when selling them.
To determine the type, it is enough to look at the muzzle and the adipose fin. In the long-nosed catfish, the muzzle and fin are much longer.
Maintenance and care of Platydoras
Water parameters for pH content: 5.8 – 7.5, water temperature: 23.9 – 30.0 ° C. dH 2 -20 °. The minimum amount of aquarium for catfish is 120 liters. Since this freshwater inhabitant is unpretentious to the conditions of detention, it is enough to change 30% of the water every month.
Like most catfish of this family, Plateidora prefers medium-hard water saturated with oxygen. Be sure that the aquarium shelters and subdued lighting. Voidings in roots or snags, clay pots, parts of plastic pipes will serve as secluded corners.
Platydoras love to dig in the soft river bottom, so good sand or gravel should be in the aquarium. These catfish do not gnaw aquarium plants and eat only small algae. With the arrival of night, the Platydoras get out of their shelters and start digging in search of food.
As a consequence, on the plants with small leaves can grow muddy plaque. To observe the activities of the fish at night, you must install the LED backlight in red or moonlight.
Feeding Platydoras. The striped catfish is omnivorous and unpretentious to the stern. In the wild, they feed on mollusks, crustaceans and detritus.
These catfish are benthophagous and feed on everything that reaches the bottom. Feed them daily.
Since Platydoras armatulus is nocturnal, the time to turn off the aquarium lighting is a good time to feed. But be careful, do not overfeed catfish!
There are cases when the fish died from overeating. The diet, mainly, should contain protein foods, as well as the vegetable component.
Somik with pleasure eat and live moths, earthworms, pipemaker. Since they eat everything that they find at the bottom, frozen food and flakes that have sunk to the bottom will fit them.
Feeding aquarium fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.
Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.
In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.
Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking.
In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry.
Detailed information on all Tetra feeds, you can find on the official website of the company – here.
It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.
Peaceable, gets on with any kind of aquarium fish. They are great for multi-species aquariums and are very friendly to their neighbors of medium and large sizes. However, small fish will be perceived as food.
Due to the strong armor on the body, representatives of this species are settled with large aggressive fish. South American Central American cichlids, large tetras and other haracin, cyprinids, gourami and other anabontis, gambusian and other somas that do not have a heightened sense of territoriality are perfect as neighbors.
Soms can be kept alone or in a group. With group maintenance, individuals will manifest territorial behavior, therefore clashes between members of the group are inevitable, but they will not cause any damage to each other. In consequence, they will even begin to share their shelters with each other.
In the wild, Platydoras gather in flocks for protection. See also article “Compatibility of aquarium fish”.
Sexual dimorphism and reproduction of plateidoras
If you look at the fish from above, it is noticeable that mature females are thicker than males. In captivity, striped catfish are bred very rarely.
It is a spawning fish, but it is bred for sale by hormonal injections. There are only isolated cases of successful spawning in the aquarium, when the breeders found already swimming fry. In the wild, Platidora females lay their eggs for fertilization in rivers and streams.
It is also known that smaller representatives of armored ones are also called nest builders. In an aquarium, they can collect various debris, or find places with leafy litter or pieces of wood and try to hide under them.
Then another fish of the same species swallows the “nest”, but even this will not be a fact of successful fertilization and subsequent reproduction.
Habitat and history of the striped catfish Plateidoras
Som was described by Valenciennes in 1840. The genus name “Platydoras” in translation from Greek means: platys – smooth, doras – skin.
In nature, soma live in South America. They are found in the Amazon Basin in Peru, Bolivia and Brazil, as well as in some other Brazilian river basins, in the Rio Orinoco River Basin in Colombia and Venezuela, Rio Essequibo in Guyana, and in the coastal drains of Suriname and French Guiana.
For many years, Plateidoras was erroneously called Platydoras costatus, until in 2008 a group of researchers led by Piorsky did not classify. The species Platydoras costatus are individuals with a limited habitat, including a pair of rivers in eastern South America.
In turn, the striped catfish Platidoras is distributed throughout South America, inhabits the Amazon and Orinoco river basins, and has been caught for sale for decades. This fish belongs to the catfish “Raphael.”
There are also two very similar species with a striped color, but living in different places. This is Platydoras costatus and long-nosed plateidoras (Orinocodoras eigenmanni), which has a more elongated face. Another very common type of Raphael is the spotted catfish Agamyxis pectinifrons, which, judging by the name, has a spotty coloration.
Platydoras armatulus lives in reservoirs with stagnant water or a weak current. In streams and wetlands, individuals lurk among tree roots or aquatic vegetation.
Somiki feed on shellfish, crustaceans and detritus. They are usually found in areas with soft sand, which are buried in case of danger.
The rainy season causes them to migrate to flooded forests, where there is a lot of food. Although these fish are territorial, in nature they gather in flocks for greater security. There is evidence that the young eat the parasites and dead scales on the body of predatory fish.
Platidoras fry are bright, striped and very similar to other species of fish-cleaners. Most likely, the striped color is a kind of signal for other fish that not the food approaches them, but the cleaner.
The stripes fade with age, and perhaps that is why the desire to clean predators disappears.
