FEEDING AQUARIUM FISH

Feeding the fish, one of the most important factors that ensure normal development and the life of the fish. From nutrition to the greatest extent depends on their appearance.

When feeding fish one should follow two basic rules: the more varied the feed, the better; it is better underfeeding than overfeeding.

Food should be given in small portions; as soon as the fish stop eating, feeding should be discontinued, and uneaten food to remove. Feed the fish once a day, preferably in the same clock. No irreversible development will not take place if for any reason the feed will not be given fish for a few days (5-8). but this should not be the rule.

Currently on sale offers many high quality brands of dry, canned and frozen feed for fish, which greatly simplifies the problem. However, for a number of fish prefer live food, as well as in the preparation of fish to reproduce is preferable to give live foods, dry — only temporarily. Continue reading

Do fish drink water?

Though marine fishes drink a lot of water, their freshwater relatives don’t drink nearly anything. The root of this difference lies in the needs of fish to maintain a normal balance of salt and water in the body.

The water in the ocean three times saltier than its own liquid environment living in the ocean fish. As a result of a natural process known as osmosis, water body sea fish rushes out through the skin and gills. To compensate the lost liquid, saltwater fish forced to consume large quantities of sea water.

The concentration of salt in the body of freshwater fish exceeds its content in the surrounding water, which is why freshwater fish do not drink, like a sea, and constantly absorb water through the skin. The excess liquid they secrete in copious urination. Continue reading

Marine aquarium

The content of the fish in a saltwater aquarium can be very challenging. Maintenance of the necessary salinity of the water and a sufficiently high oxygen level in it even in a well – equipped aquarium is not easy. Most marine fish bred in aquariums, is habitat, so these fish cannot tolerate fluctuations. Reef the oxygen level is always high and a lot of light, because the corals grow only in shallow and clean water.

Sea water is very corrosive, so the aquarium must be made entirely of glass or plastic, without metal parts. Although marine fish are less inclined to jump out of the vessel compared to freshwater, the aquarium must be carefully closed to avoid contamination. It will also help to control evaporation: when water evaporates, salinity increases, so the vessel should be topped up with distilled water. Continue reading
