Live bearing, exotic fishes are 
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.

CICHLIDS 
Most of these fish are from 
South America. The Amazon Ba- 
Sin offers quite a variety of 
these miniature foreign fishes. 
The Scalare or Angel Fish is a 
member of this family, as are all 
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.
