SCAVENGERS 
FOR AQUARIUM USE 
EVERY AQUARIUM OR POOL SHOULD HAVE 
SCAVENGERS 
SCAVENGERS are the housekeepers of the aquarium and relieve you 
of that responsibility. Snails devour algae, decayed matter, and eat 
unconsumed food. Tadpoles eat many of the impurities in an aqua- 
rium and are particularly helpful with goldfish. Clams or Mussels act 
as a continuous filter to keep water clear. IN AN AQUARIUM, USE 
AT LEAST 3 SCAVENGERS TO A GALLON OF WATER.
