288 FRESH-WATER AQUABIA. 



in an aquarium in almost any numbers, but they will soon be reduced 

 to a very small one, as they are exceedingly voracious, pugnacious, and 

 regular cannibals. 



Many other animals besides the few indicated may be kept in an 

 aquarium, but overcrowding will cause great mortality. If convenient, 

 it is well to have several large tanks, so that those animals wliich will 

 not keep the peace with their fellow-lodgers may be separated. It is 

 also a good plan where objects for the microscope are specially wished 

 to be always at hand, to have one tank very stagnant, i.e., where the 

 conferva is encouraged to grow vigorously and never cleaned out ; but 

 if the hints given above are followed, a great number of species may 

 be kept and will flourish in a single tank.
