. Goldfish varieties and tropical aquarium fishes; a complete guide to aquaria and related subjects. Aquariums; Goldfish. Fig. Sg. Rasbora hetcramorpha (Slightly enlarged) Of a light reddish color, with a vivid triangle of black on the side, this fish is most striking in appearance, particularly in a small aquarium. It lives for years if kept at a warm temperature, but it is difficult to breed, nobody in the United States having yet succeeded in propagating them. Here is an opportunity for a clever aquarist to accomplish something well worth while. See pages 253 (B la) and 260 (N 1).. Fig. po.

Torpedo eleetricus (Electric Catfish) This most curious aquarium fish, when taken in hand, gives an electric shock which may clearly be felt as high as the elbow. How this is accomplished is not clearly understood, as it is supposed to be necessary to touch two electric poles to receive a current, li the head and tail of the fish were the poles, the current would only pass from one part of the hand to the other, instead of up the arm. The fish is able to cause the shock either in or out of the water. This is doubtless a means of self-defense, as the current is scarcely strong enough to kill a victim intended for food.
