I've had my cichlids for more than a year. I had 3 jewel cichlids before and there was a pair, they laid eggs once before ( but that was before one of the other cichlid died). So now that I had 2 left, I was hoping one of these was a female and male. One of the cichlids has a budging tummy and the other one is more on the slimmer side. Please do help me confirm their genders
