Kribensis Cichlid - female pregnant?

Well, judging by my kribs breeding and behaviour, they like to have a cave (in my case, a fake ornament cave thing) to spawn in. They won't spawn on leaves or the bottom of the tank. Also, the female will almost arch her body and "shake" or "vibrate" in front of the male to get his attention, if he isn't already interested in her. Then she swims into the cave and the male follows her. She will swim in and out several times and usually I can tell when there are eggs in the cave because she pretty much stays in the cave the whole time for about 2 or 3 days (i don't see her) and the male almost seems to guard the cave. Then a few days later there are babies! Yay. Males have a longer pointed dorsal fin and the pink on their bellies is not as bright, their tails are also more pointed or spade shaped where the females tails are round. The first pic is a Male (his tail has a chunk missing, the tails aren't normally like that) and the second is the female. Hope this was kind of the answer you were looking for??
