I got some multi cichlids a few weeks ago hoping to get them breeding. Are the large ones always males? Do I have one male and four females? I just have to mention how fun these fish are. The larger one looks about 1.5 times the size of all the others. It and one other small one decided to dig themselves homes under the rocks despite the 48 shells in there. How big should they be before they can breed? The small ones are about the length of an almost full grown mystery snail as you can see in one of the photos.
