Fish/Convict Cichlids

Question
Hello Ron,
  I have some questions about some convict cichlids that we have. i noticed that two of the are always together one is bigger than the other one. We think they might be a couple so we separated them from the rest and put the on a different aquarium. did we do the right thing? we did this because in the past we had a couple that would lay little eggs but the other fish would eat them. also if we separated both parents do you think that the father will eat the eggs too?/ thank you for your help in advance.

Answer
Hi Heber,
 Female convicts almost always have some orange color on the belly, whereas males don't.  

If they lay eggs, and they are a pair, they are usually very good parents, i.e., the father typically does not eat the eggs.

Expertise

I am an expert on cichlid fishes, particularly New World cichlids. My broader expertise includes the behavior, ecology and reproduction of fishes in general. (I am NOT an expert on Goldfish). Please do not use abbreviations, such as "my GT has a swollen eye" because I don't know what a "GT" is. The more clearly you can explain your question, the better chance I have of understanding what it is that you seek. I keep fishes both as a scientist and as a hobbyist and I currently maintain about 140 aquariums.

Experience

I am an Associate Professor at the California State University, Sacramento in the Department of Biological Sciences, and I run a website, called the Cichlid Research Home Page . I also write for many popular aquarist magazines, and I was editor of Cichlid News magazine for several years. I am a scientist and I spend my time teaching fish biology, ecology, behavior and evolution and doing research on the reproductive biology of fishes, particularly cichlids. I do research in the laboratory and in Costa Rica, Nicaragua and Mexico. My main interest is understanding the evolution of parental care in fishes. I am interested in encouraging greater public awareness, understanding and participation in science.
