198 Fresh Water Aquarium 



Should it miss the first time, it swims around 

 the vessel until it finds itself again opposite 

 the insect, when the attack is renewed. 

 Travelers found this fish in Japan about the 

 middle of the last century and reported that 

 it was kept in tanks and little ponds with a 

 stick in the center. On this stick insects 

 were fastened with a thorn and before long 

 the fish would make an attack upon them, as 

 described above. Brehm confirms these re- 

 ports in his beautiful book "The Fishes." 



The Chanchito (Her os fascctus), a native of 

 South America, is found in ponds and slowly 

 flowing streams and rivers in the watershed 

 of the La Plata river. Very easily cared 

 for, satisfied with a small aquarium, it is a 

 good fish for the amateur aquarist, never 

 failing unless the water should be kept too 

 cold. While in cool water its coloring is 

 not brilliant, it is very beautiful in a higher 

 temperature. 



In shape it is a rather compact fish, of 

 medium length, with a strongly convex back.
