Expecting Babies???

Noticed that one of my White Cloud is getting exceptionally fat. Did some google to confirm my doubts.. I think she is expecting.. also noticed one of the males (of the 3 White Clouds, two were males) has been constantly chasing this female.. I find the couple doing several weird acts behind the decorative plants... hard to tell whether its some kind of mating ritual!! Will soon findout.. I also found out that White Clouds (unlike many other fishes) dont eat their fry. I am excited.. but at the same time, I am a little worried.. will my tank support more fishes? (Remember I am planning to add 3 more fishes this weekend.. may be I have to delay that for a while!) What do I have to do in order to take care of the babies? I read somewhere that they cant eat the regular fish food.. they need special stuff..
