Live bearing, 
very popular with the amateur, as 
no experience is necessary in or- 
der to breed these successfully. 
All you need is a good grade of 
prepared fish food so that the fish 
will have the proper nourishment, 
and nature will take care of the 
breeding end of it. Provide fine, 
bushy plants in the aquariums or 
separate the females and put 
them in a bowl by themselves 
when they look like they may be 
ready to have young. 
GUPPY 
Live Bearer 
Everyone acquainted with tropi- 
eal fish knows the Guppy family. 
They are all very hardy and very 
prolific; being colorful and small, 
they can be kept in small vases | 
and glass jars. The males reach a 
length of 1% inches, whereas 
some females will get as large as 
2 inches; average size about 14 
inches. All of our quotations are

CICHLIDS

South America. The Amazon Ba- 
sin offers quite a variety of 
these miniature foreign fishes.

the other varieties listed under

this heading. Most all of them 
lay their eggs on hard, smooth 
surfaces and when the eggs are 
hatched, take care of the young. 
An exception to this rule is the 
mouthbreeder. The female carries 
the eggs in her mouth for about 
ten days to two weeks in a spe- 
cial pouch. Their interesting 
breeding habits, and also their 
beauty, has made Cichlids one of 
the aquarist’s favorite fish and no 
collection is considered complete 
without them.
