A little background: I'm just a high schooler with a 55 gallon tank and 3 convict cichlids. 2 pink females (sisters, around 1.5 to 2.25 inches) and 1 blue convict (which I assume is male). I plan on breeding my convicts and getting a marble variety, as my females carry the marble gene. So my question is, my two females have different body shapes. One is long and slim, the other "regular" short bodied. Which body shape do people perfer?
