SCAVENGERS 
Goldfish are very beautiful, so are Water Lilies and all 
aquatic plants. Snails, tadpoles and fresh water mussels aid 
in purifying the water and sand. Just as the Goldfish eat 
insect life and mosquitoes, so do Snails consume algae and 
green scum; Tadpoles eat decayed matter as well as the 
excrement of the fish. They are of inestimable value both in 
pools and aquariums. 
The transformation of a tadpole to a frog is not only an 
interesting but an instructive natural phenomena. All will 
enjoy seeing the legs develop and the tail absorbed and 
finally the real frog. 
You will surely want with your fish and lilies these scav¬ 
engers to help keep the water pure and clean. 
TADPOLES. One of the best scavengers. They do not 
eat fish eggs and are harmless to the fish. Per dozen 50c
