Ok,so I have 5 african cichlids, in a 30 gallon tank! 2 yellow labs, 2 red zebras, and one that i'm not really sure what it is! 1 of the yellow labs, and one of the red zebras, have a bigger belly than the others! is it possible that they are pregnant or are the sick? they are only about 1-1.5 inches in length! Are they big enough to mate? and how do i tell if they are male or female?
