Abstract
The Cichlid Fry Project investigates the relationship between egg size and fry size among various species of cichlids and demonstrated a relationship between egg size and fry size. However the project hasn’t incorporate mouthbrooder cichlids because mouthbrooders exhibit a different breeding system and typically lay few but large eggs. It is unknown if mouthbrooder egg size and fry size follow the same positive relationship as substrate-spawning cichlids. Analysis of the mouthbrooder egg size and fry size shows the same positive relationship between mean fry size and effective egg diameter as substrate-spawning cichlids.
