As soon as at the end of 1980 a photograph of a zebra number catfish was first published (L046), among aquarists, a real boom began on these fish. And then fish hunters from South America quickly realized that they can earn very well. In search of new places for fishing, they began to go farther and farther into the rainforests. And as they moved deeper into the jungle and caught catfish for sale, they began to discover more and more new species. And so quickly and much that scientists simply did not have time to describe and catalog them. Therefore, they simply began to assign the Latin letter “L” and a serial number to all new types. Where the letter “L” means the name of the family, Loricarium or Mail Som. And today som with the letter “L” already exists around 600 species.

Over time, they had other names associated with their beauty. But they still have their room. Here are just some of the unusual names of these fish: L200 "Green phantom" L184 "Ancistrus diamond", L340 "Mega clown", L134 "The leopard frog", L260 "The Queen of Arabesque", L052 "Butterfly".

As I wrote above, license catfish or loricarids, there is a huge variety of species. But they all share a few common features. First, the lack of a swim bladder. That is, they can not swim freely, and, as it were, jump from place to place. Secondly, all species have a similar body structure. Big head with powerful muscles and a mouth in the form of a sucker with many small teeth. This structure of the mouth helps them to feed and hold in one place. Since many of them live in reservoirs with fast currents, their bodies eventually acquired a drop-like shape, with excellent aerodynamics. And a large dorsal fin in the form of a sail and a powerful tail fin steering wheel helps to control such a body in a stream of water. Which are great help them when moving.

Numbered soma have not only common features, but also a huge number of interspecific differences. Basically, these differences relate to the size and color of the body. Mostly these are small and medium sized catfish that are ideal for most aquariums. But among them there are real giants who need a huge bottom area with shelters and the flow of water.

This photo was taken at the Taiwan Aquarium Show at 2012. It depicts Panak chain catfish (Panaque), 60 long, see. And as its current owner claims, the catfish has already changed three owners and has been living in aquariums for more than 60 years. However, he is constantly growing.

By body color, different species can be very different from each other, so they can be practically indistinguishable from each other. It is also worth considering that they may change with age or depend on the color of the bottom surface. This creates even more confusion in their description and systematization in the species catalog.

But it is safe to say that all types of mail soms are insanely beautiful and original.

The maintenance of license catfish in an aquarium usually does not cause any particular difficulties. There are really a few prerequisites for the well-being of your pets.

Since almost all kolchuzhnye catfishes are bottom-dwelling, then aquariums should be chosen with a large bottom area. They also need many different hiding places. Otherwise, the fish will be under constant stress, which will affect the brightness of the color and affect their health.

In terms of nutrition, there are both vegetarians who eat green fouling of algae in an aquarium, as well as carnivorous species. But for the most part, these catfish eat both of them, and there are usually no problems with food in the aquarium.

❗Important! All armored catfishes, and common bristlenose catfish (Ancistrus dolichopterus) including, it is necessary to have natural snags in the aquarium. Enzymes from their surface are involved in the digestion of catfish and affect the quality of their life!

There is one more important point in the maintenance of chain som. And it is more important for their owners than for the fish themselves. This is a question of lighting in a catfish aquarium. The fact is that most of them are night fishes and in bright light it will always be in shelters. Therefore, they are better kept in a specific aquarium with dimmed lighting. In such an aquarium, the fish become much bolder. Otherwise, you have to sit at the aquarium with a flashlight at night to admire their expensive beauty.

General recommendations for the content:
  • The volume of the aquarium is from 80 liters.
  • The water temperature is 25 ° -30 ° C.
  • Weekly substitution - 25-30% of the total.
  • Feeding: vegetable food, special feed for catfish, bloodworm, artemia.
