. Goldfish varieties and tropical aquarium fishes; a complete guide to aquaria and related subjects. Aquariums; Goldfish. 82 GOLDFISH VAKIETIES AND extremely handsome fancy carp of Japanese breeding, having blue backs, red sides, white bellies, and with the large irregularly placed scales of the Mirror Carp. It is to be hoped these will be propogated here.. Fig. 69.

It is operated by a quick overhead swoop and the net pulled rapidly over the bottom towards the fisherman.
