Sea hare: fish from the Pacific ocean

Description fish-rabbit

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.

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.
