Sea hare: fish from the Pacific ocean

Description fish-rabbit

Sea hares are most common in the Western Pacific, the Mediterranean and the tropical waters of the Indian ocean. They have a medium size and oval body, flattened laterally, covered with minute inconspicuous scales. The head of the sea hare has a triangular shape and slightly elongated snout with a small mouth at the end. Sea hare is able to defend himself – for this it has sharp rays on the fins with poison glands, injections which cause quite severe pain.

Sea hares can change their color and intensity depending on their condition. Usually the fish-hare can be found in algae and lagoons, where they live among swarms of young fish and fish-surgeons. Most of the day sea hares spend for chewing low-calorie food in the form of algae from coral reefs – so they provide a right amount of nutrients.

Despite the presence of venomous glands, this species is quite popular for human consumption, particularly among island residents, who also sell locally caught sea hares in Korean, Taiwanese and Philippine markets. Continue reading

Fish or fishes?

Fish enliven the garden pond and justify their presence in it that eat mosquito larvae and other insects. However, the presence of fish in the pond is desirable, but not necessarily, because usually has little effect on the maintenance of the purity of water.

When choosing fish, primarily guided by the size of your pond. If you are not strapped for cash, you probably will want to buy expensive beautiful carps. Unfortunately, these fish are harmful to the plants-oxygenators. Like other species of carp, they need a reservoir with a surface area of not less than 7.5 sq. m. At the other end of the scale are hardy and plain ordinary goldfish and shubunkin that can live in any, even very tiny pond — it is necessary only to ensure that in winter the surface water is not delayed by ice for a long time. Between koi and goldfish is Golden Orff, which required a pond with a surface area of at least 3.5 sq m. Another important consideration is whether will be visible to fish.
