Agonus decagonus (Seas ferret)

Close to sea mouse, it is smaller, but lives in a larger depth.

The Agonus Decagonus fish is a small fish from the Agonidae family, commonly known as "fish-bourreau". It is mainly found in the cold north Atlantic waters, especially around the coasts of Iceland and Norway. The body of these fish is elongated and compressed laterally, with a wide head and round eyes. They generally have a brown-grayish coloring with dark spots on their body and white stripes along their belly.

Their name "fish-bourreau" comes from their aggressive behavior towards other fish. They are able to sneak into rocky anfractits and surprise their prey by attacking them in behind. They mainly feed small fish, crustaceans and molluscs.

The fish fish have a relatively short life expectancy, reaching only a few years in a natural environment. They generally have a maximum size of about 20 cm, although some specimens can reach a larger size. They reproduce in periods of Frai, with females laying their eggs in rocky cavities or crevices. The eggs are then fertilized by the males and incubated for about a week before the blossoming of the larvae.

Due to their limited distribution and their aggressive behavior, the fish-burning is not a very common fish in the aquariophilia. However, they can be found in certain public aquariums and are appreciated for their unique character and their interesting behavior.
