Live Bearers 
(Viviparous Killifishes) : 
These Fish Bring Forth Their Young Alive 
Live bearing, exotic fishes are very popu- 
lar with the amateur, as no experience is 
necessary in order to breed these success- 
fully. All you need is a good grade of pre- 
pared 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 them- 
selves when they look like they may be 
ready to have young.
