Silverfish Argos: everything you need to know

The Argos fish is a type of fish that can be kept as a pet, but there are some aspects that are important to know about.

Silver fish Argos too scientifically known as Selenotoca Multifasciatathe meaning of which is “scavenger”, belongs to the family Scatophagidae (scatophagids), a family of fish from the kingdom Animalia, from the phylum Chordata, from the order Perciformes, distributed both in sea waters and in lakes and rivers of the Indian Ocean and the western part of the Pacific Ocean. They are a gregarious species, meaning they tend to group together and stay in a group.. In captivity, its length usually does not exceed 20 cm, but if found in the wild, this animal can reach 40 cm.

Types of aquarium

Before purchasing this type of fish, it is necessary to have some knowledge about the chemical composition of the aquarium water sold in order to reproduce it in our aquarium. You can start using fresh water for young fish., which bear protection like a bony shield on their head and back, which decreases over time as they become adults. At this stage it is also important not to place plants or seaweed around him because he will eat them unless we want to offer them to him as food.

However, as they grow, the salinity will have to be increased until a brackish and spacious aquarium is achieved, since their liveliness means they need to form schools and swim over a large area. Finally, Due to the large size these fish reach, they can only live in large community aquariums with species of similar origins and requirements.that is, in marine aquariums with a volume of more than 400 liters, which have formed coastal or mangrove areas with many vertical roots.

When getting Argos fish, you need to consider the type of aquarium.When getting Argos fish, you need to consider the type of aquarium.

Despite this, in these natural mangroves the salt in the water is not constant as it changes with the seasons and the tides. It is best to achieve good results in A brackish aquarium, that is, with little salt, means that the water is four parts fresh water and one part sea water.so the density will be around 1.005 and the pH around 7.6.

You also need to be careful with movement, with aeration, because this water cannot contain as much dissolved oxygen as fresh water. These pets when They are older and do better in a saltwater aquarium with a density of 1.020 to 1.023..

A brackish aquarium can be decorated with roots, rocks, and peripheral plants, leaving plenty of space for swimming. A good option is rice plants. To prevent the silver argo fish from eating the plants, you need to give them the vegetables that they like the most.trying lettuce, spinach, chard, etc.

Water conditions

Water conditions are also very important. If it is fresh water, then it should be brackish and alkaline water up to 8º Ph, moderately hard or very hard water up to 14º Kh. The point is that these waters that they will find themselves in when they are young have varying levels of salinity throughout the day, and this characteristic allows new hobbyists to get practice when it comes to water chemistry. On the other hand, if it is salt water, the appropriate density for a reef aquarium is between 1020 and 1024. The temperature will always be between 20 and 28 degrees Celsius.. Although they live in fresh waters when they are young and then migrate to the sea as adults, we can also find them in the coastal zone of Australia, New Guinea and New Caledonia.

Feeding

It is an omnivorous species because They eat all types of foods: ojas, lettuce, spinach, oatmeal, cooked rice, commercial tropical fish food such as pellets, sticks and tablets, etc.. You can offer both live food and algae, which can be given as a mixture, such as Porphyra umbilicales and Porphyra Yesoensis or Palmyra Palmata, or frozen food can be given.

Playback

It should be noted that no obvious sexual dimorphism in Selenotoca Multifasciata and that there is no information about its reproduction in captivity. There are two theories about spawning regarding this: Firstly, adult individuals enter rivers to spawn and, having reached more or less maturity,, they go to the sea. The second theory suggests the opposite, that spawning occurs at sea on coral reefs, and then the fry enter rivers to grow and, as adults, migrate to the sea, never to return.

Aspect

As for the appearance, it is a fish that appears to be compressed from the sides and you should be very careful because its dorsal spines contain a little poison and it is not that it is dangerous, but it can cause a lot of pain if you get caught into her. punctured In addition, they have a very pointed shape..

The fins of this animal have a typical petiform structure: the anal and dorsal fins are divided into two parts: the back with soft rays and the front with spiny rays. As for its pelvic and pectoral fins, it should be noted that they are located exactly vertical in relation to each other.. The dorsal fin starts vertically further back than the ventral and pectoral fins. The dorsal fin has 16 soft rays and 12 spines. The anal fin has 4 hard spines followed by 16 soft rays.

Thanks to the steep profile, the head is clearly separated from the body, especially compressed in the dorsal part. The silver argos fish has a small horizontal mouth., non-protruding, that is, not protruding, and with teeth forming several rows. Their eyes are large and protruding, but not too round.

Color

On the other hand, it is true that its color varies depending on the origin, age and origin of the animal, but They are usually yellowish-silver in color with green tones., olive, although instead of silver it can also change color to ocher. They are characterized by dark black vertical lines that begin on the back and gradually fade in and out along the body until they become dots of the same color, thus dominating the lower half of the body. However, this does not happen in adult fish.

The color of Argos fish is very characteristic.The color of Argos fish is very characteristic.

The edges of the anal, dorsal and caudal fins of this pet are also black, and this color fades over time, like the color of the body. The back of the head and the head of this animal have green and yellow tones.

Difference from other species

As for how they differ from other species, it is true that this pet It is usually confused with Scatophagus tetracanthus and Scatophagus argus in its juvenile phase.. However, the silver argos fish has a longer body and a narrower interray membranous space of the fins. The general outline of the body is hexagonal, like most scatophagids. Despite this, its caudal peduncle is longer and covers one fifth of the length of the caudal fin. Another difference is the pointed shape of the mouth and large eyes.

marine aquarium hobby

This type of pet is especially suitable for those people who love fresh water and for those who want to start diving into the great adventure that is the saltwater aquarium hobby, that is hobby raising fish and other aquatic organisms in an aquarium under controlled conditions.? And the silver argos fish is a species that, due to its nature, perfectly tolerates any variations in the chemical composition of water, and even more so when it comes to salinity.

The hobby of marine aquarium keeping has grown significantly over the centuries since its origins two thousand years ago, when goldfish were kept for decorative purposes in ponds and containers. There are also references in ancient China to breeding goldfish in ceramic tanks at room temperature.. The level of this practice was very simple and did not have life support systems for these pets, as they required constant changes of water and required strong species for this. This problem has been strengthened to this day by aquariums and can be overcome with the development and advancement of the modern aquariums we have today.

There are many people who are interested in aquarium keeping.There are many people who are interested in aquarium keeping.

Golden varieties of Carassius auratu, a medium-sized carp with great durability and coloration, were the first fish that could be kept in small ceramic vessels. This was not easy as they had to withstand the difficult maintenance conditions prevailing at the time. Nowadays, the aquarium hobby is a practice capable of achieving a high level of knowledge and sophistication, transcending the boundaries of the hobby and becoming a real science, that is, we are talking about aquariumology.

Thanks to the development and improvement of technology, fish farming and sea salt, marine aquariums became popular in the late 1980s. Thanks to this, today we can have a home reef aquarium, because previously only clownfish, dragonflies and pomacanthids could be part of it. What is being done in reef aquariums now is to limit the number of fish. and increase the volume of live rock and other invertebrates such as cnidarians.
