Fig. 265. Tilapia tnacrocephala 

 In this instance the male carries eggs and young in his mouth. It he is caught 

 in a net. he is very likely to spit them all out. This does not mean they will not 

 hatch. They may do so, but should be in clear, clean water, and be gently stirred 

 several times daily. The eggs are very large, resembling mustard seed in size and color. 

 Hatching takes about a week. The young are mere threads attached to the egg, but 

 in another two weeks they completely absorb the yolk-sac and become quite sizable 

 fish. In adults the male has opaque gill plates. The female has a transparent pinkish 

 area about where the high light shows on the gill plate in the photograph.
