The fish – telescopes bulbous rounded body. Its height more than half length of body. The fish have lengthened (up to ¾ of body length) two-bladed tail fin hanging down. The fin on the back stands upright. All other fins – long veil. The name telescope fish was at its largest (about 2 cm), protruding (bulging) eyes. The diameter of the eyes of the instances that took in Shanghai, up to 5 cm Fish – telescopes differ in the length and shape of the fins, color, presence or absence of scales and many others. Telescopes with a tail fin similar to a skirt, usually called a skirt, but if the tail is in the shape of ribbons — strip telescopes.

The black body of the telescope is covered with scales, which is in straight rows.

Telescopes that have symmetrical black and white color are called pandas, but if the torso is painted white, and panicipant black — billed magpie. Distinguished several types of telescopes, depending on the size, shape, and directions of the axes of the eye. Your eyes basically are: disc, spherical, spherical, conical and cylindrical.

Stargazers have a small long forked tail, and lack of dorsal fin. Continue reading

Fishing for beginners.

As a nozzle for catching saltwater fish are great crabs, shrimp, mussels, sea fleas, sea worms, snails, animal spleen, and pieces of fish.

Typically large marine fish prefer to bite on the fry, fish fillet served, but also on crabs and shrimps (mackerel, sea cocks, Napoleon fish, flounder, etc.). Worms and maggots are suitable as a nozzle for catching smaller fish — sea bass, perch, goby, mullet, etc.

The lure of crab will attract primarily sea perch, wrasse, and goby. Crabs can be caught with hands in the coastal rocks. There is another effective method of catching crabs: tie to the edge of the twine or thick twine a piece of raw meat or fish and drop the bait between the rocks. Crabs will react to such a treat and clung to him. Crab meat can be stored in the freezer for a few days, before attachment to the hook it should be defrosted. Live crab can be stored for a short time in a bucket of cold water and seaweed in a cool dark place. On a hook baited with meat crab by removing the claws.

Shrimp is an indispensable nozzle for saltwater fish with a float and bottom fishing rods. Mined shrimp in the thickets of seaweed, as well as in freshwater reservoirs of the Far East. Obychno shrimp caught using nets, in which as bait, put the pieces of bread and meat. Nets set in the thickets of sea grass at a depth of 3-4 m Caught shrimp wrapped in wet cloth and stored in a cool place. To save the shrimp for a few days, they are boiled or salted. Shrimp skewer on the hook (for fishing) or using only the neck (for small). Continue reading

Marine fish: breeding

Reproduction and spawning

Reproductive behavior of tropical marine fishes is poorly documented because only a few species breed in captivity. However, some – such as clowns, gobies and seahorses to breed relatively simple. Others, like coral fish may spawn in the aquarium but the fry are so immature that they are very difficult to grow.

To ensure availability in the aquarium at least one opposite-sex pairs marine fish breeding is almost impossible, because in most species males and females are externally indistinguishable just. However, if you keep the fish in the pack, their behavior will help you to determine the sex charges. If two identical fish fight is most likely male contesting territorial rights. If two fish are related to each other friendly, it can be compatible in a female and male. Unusual swimming movements or postures may not be indicative of flirting – so, in your aquarium just got a couple. In the mating season sometimes appear insignificant physical differences: the female has, of course, the belly is inflated from the calves. Males often intensifies the color, and the picture loses clarity. Some species are able to change their gender, what does not prevent, but rather contributes to the search for a pair for spawning. For example, all multiclone – males, but if you have a small group (two individuals), the dominant fish will become the female and will mate with the nearest dominant male. Kood I-frames and some coral sex change occurs in the opposite direction: the dominant individual in a purely female group turns into a male. Continue reading
