THE GOLDFISH AND ITS CULTURE. IOI 



stopping to make the vain attempt to remove something from their 

 gills that annoys them. They are apparently coughing. Their 

 appetite decreases. It is evident that the gills are out of order, 

 they thus failing to take up oxygen for the blood. 



As the disease progresses the fish becomes lean, as seen back of 

 the head, on the back, and the sinking in of the abdomen, causing 

 the head to appear too large and out of proportion. The gills 

 become agglutinated which results in the destruction of their 

 structure by decay. Having arrived at this "stage the fish is too weak 

 to balance itself and swims head downward, finally standing on it, 

 because it is the heaviest part of its body, and dies in that position. 



The duration of this disease varies in different individuals and 

 seasons, it being of shorter duration during cold weather. 



The origin of this disease may be traced back to unnatural 

 treatment while in captivity, as fish in native waters never get it, and 

 in well managed aquaria they very seldom have it, while in those 

 badly managed they frequently die of this disease. The cause of 

 the disease arises from invisible organisms called tubercular baccillce, 

 these being inhaled by a fisji whose breathing apparatus is in the 

 least out of order, infest these organs and destroy them. 



The disease proves fatal in all cases, or has invariably done so in 

 the writer's experience, who has so far failed to discover an effective 

 remedy. The disease may be avoided by keeping the aquarium in 

 perfect condition. 



SLIME OR ITCH. 



This disease generally appears during the colder season of the 

 year, seldom manifesting itself when the weather is warm or hot. 



The body of the fish becomes coated with a layer of some whitish 

 substance, the deposit beginning on the back near the head.
