CHAPTER X, 
GENERAL MANAGEMENT. 
There now remain a few remarks to be said in regard to 
the general management of an aquarium. I say a few remarks, 
because if the aquarium has been properly started it almost 
takes care of itself; all that is necessary is to feed the fish 
regularly every day. One person only should have charge of 
this, and the fish should be fed as nearly as possible at the 
same period. Allow for each fish its mouthful of my con- 
densed fish food, “IXL,” each feeding time. Should any un- 
consumed food remain at the bottom, the tadpoles and snails 
will devour it. 
The light for the aquarium should be under full control, 
for although the collection requires a good light, the direct 
rays of the sun are injurious to it and should therefore not 
reach it. A newspaper placed over the side facing the sun, 
when it shines, is often sufficient protection. 
Once or twice a week the inside of the glass should be 
cleaned with the wiper, thus preventing algae covering it 
and obstructing the view. This wiper is a flat sponge or 
thick piece of felt securely fastened to an appropriately 
shaped metal plate on the end of a stick, or on the flattened 
and wider end of the stick itself At the same time the water 
lost by evaporation should be replaced. A scum that may 
be present on top of the water is removed by sliding pieces
